Analog Devices Inc./Maxim Integrated MAX301CPE

Introduction to the MAX301CPE+ by Analog Devices/Maxim Integrated

The MAX301CPE+ is part of the robust MAX301 series by Analog Devices/Maxim Integrated, delivering precision and high-speed switching functionality through a dual-channel Single Pole Single Throw (SPST) normally open configuration. Housed in a standard 16-pin PDIP package, this analog switch supports multiplexer/demultiplexer operations with a maximum on-state resistance of 35Ω, channel-to-channel matching within 2Ω, and reliable operation across supply voltages from +10V to +30V (single supply) or ±4.5V to ±20V (dual supply). This makes it suitable for a broad range of engineering tasks demanding both accuracy and speed in signal routing.

Main Attributes of the MAX301CPE+ Family

The MAX301CPE+ distinguishes itself with several advanced specifications tailored for demanding analog switching scenarios. Notable features include:

Low on-resistance (typically 22Ω, max 35Ω), ensuring minimal signal loss.

Channel-to-channel matched resistance under 2Ω, essential for precision signal processing, particularly in differential applications.

Resistance flatness guaranteed to within 3Ω across the entire analog signal range, optimizing linearity.

Exceptional off-channel leakage (max 6nA at +85°C) and on-channel leakage, minimizing unwanted signal paths and enhancing isolation.

Fast switching times—150ns typical for turn-on and 100ns for turn-off—vital for real-time and high-frequency signal handling.

High off-isolation and crosstalk specifications: -90dB at 1 MHz crosstalk and 72dB off-isolation, ensuring clear signal separation in densely routed designs.

TTL/CMOS-compatible logic inputs and rail-to-rail analog signal support, maximizing integration flexibility.

Low charge injection (<15pC), critical for applications such as sample-and-hold circuits where signal integrity is paramount.

Designed for single or bipolar supply operation, permitting versatility in interfacing with a variety of system power architectures.

In-depth Electrical Specifications of MAX301CPE+

The MAX301CPE+ supports broad analog signal voltage ranges, from V− to V+, matching supply flexibility with performance. In nominal use at V+ = 15V and V− = -15V, on-resistance remains within 30Ω at room temperature, with variations under temperature and voltage accounted for in design and specification. Linearity of the on-resistance and minimal leakage currents allow its effective deployment in analog sensitive environments. Switching characteristics, such as sub-200ns propagation times and break-before-make delay, are engineered for reliability in rapid signal selection and multiplexing designs. On-capacitance is held to 39pF (typical), and off-capacitance at 12pF, constraints which contribute to overall bandwidth (3dB frequency response well above typical application needs).

Physical Dimensions and Packaging Details for MAX301CPE+

Mechanical integration is streamlined through the MAX301CPE+'s 16-PDIP package (7.62mm body), suitable for through-hole assembly and prototype environments. Pin assignments are optimized for practical PCB design, with clear separation between analog and logic/control inputs. The package design facilitates straightforward replacement and testing, and ensures compatibility with established DIP socket layouts.

Compliance and Environmental Factors for MAX301CPE+

Engineered for reliability, the MAX301CPE+ fulfills ROHS3 compliance and is REACH unaffected. The device has an unlimited moisture sensitivity level (MSL 1), facilitating standard storage and reflow soldering without special handling. The ambient operating temperature range is 0°C to +70°C for commercial variants, with extended temperature options available within the MAX301 series. Export control status is classified under EAR99, and the part is categorized for easy customs and regulatory processing under HTSUS code 8542.39.0001.

Common Use Cases Featuring the MAX301CPE+

The MAX301CPE+ shines in a variety of professional signal switching environments, including:

Sample-and-hold circuits, where low charge injection and fast switching are crucial for maintaining accuracy.

Test equipment and communication systems that require reliable, low-distortion analog path selection.

Battery-operated devices, benefiting from the series’ low operating power and leakage.

Military radio, heads-up displays, and aerospace guidance/control systems, where high isolation and predictable performance are necessary.

PBX/PABX systems and other telecommunication platforms demanding robust multiplex/demultiplex signal management.

Design Guidelines and Technical Insights for MAX301CPE+

Effective deployment of the MAX301CPE+ in electronic systems mandates attention to power supply sequencing and logic level compatibility. It is advisable to sequence V+ prior to VL and V−, protecting the device against voltage overstress during power-up. When used at logic supply voltages other than +5V, the IC operates seamlessly at CMOS logic levels, extending its applicability to modern mixed-signal and low-voltage designs. Adding small signal diodes for overvoltage protection is recommended when strict sequencing is not feasible, with the acknowledgment of a slight reduction in analog voltage range. The thermal derating of power dissipation above +70°C must be considered for high-density and industrial deployment.

Alternative and Substitute Options for MAX301CPE+

Engineers facing sourcing challenges or broader system compatibility requirements may consider the following equivalent models within the Maxim Integrated/Analog Devices portfolio:

MAX301CSE (16 Narrow SO package) and MAX301CJE (16 CERDIP package)—providing equivalent functional performance in alternative packages.

Extended temperature variants (such as MAX301EPE, MAX301ESE, MAX301EJE, MAX301MJE, and MAX301MLP) for industrial and military applications.

The MAX303 (SPDT) and MAX305 (DPST dual-switch) series for systems requiring richer channel selection or switching topologies.

These alternative models share the core characteristics of low resistance, fast switching, and high isolation, but differ in channel configurations and mechanical formats to address specific system design requirements.
