STMicroelectronics M74HC08RM13TR

Summary of STMicroelectronics M74HC08RM13TR AND Gate IC Features

In modern digital system design, reliable logic gate ICs are foundational to implementing robust and high-speed signal processing. The M74HC08RM13TR by STMicroelectronics is a quad, dual-input AND gate IC, housed in a space-efficient 14-pin SO package. Fabricated using advanced silicon gate C^2MOS technology, the device combines CMOS speed with low-power operation, making it well-suited to high-frequency logic environments, battery-powered systems, and compact PCBs where both reliability and efficiency are paramount.

Key features of M74HC08RM13TR include high switching speed — a typical propagation delay of 7 ns at V_CC = 6 V — and ultra-low power consumption, with maximum ICC of just 1 μA at room temperature. Balanced output drive capability, high noise immunity, and compatibility with legacy 74 series logic make the M74HC08RM13TR a versatile choice for embedded designs requiring clean logic transitions and protection against electrical disturbances.

Pinout Diagram and Logic Specifications of M74HC08RM13TR

Understanding pin layout and logic symbols is essential when integrating the M74HC08RM13TR into signal chains. The device’s 14-pin SO package arranges four independent two-input AND gates, each with distinctive input/output pairs. The standardized pin configuration allows drop-in replacement or integration with legacy designs following the 74 series 08 layout.

Logic characteristics include symmetrical output impedance (I_OL and I_OH both ≥ 4 mA), ensuring balanced drive for both logic high and low output states. The truth table for each gate follows canonical AND logic — outputs are high only when both inputs are high. Consistent propagation delay times across transitions further facilitate timing-critical designs and synchronous operation in complex digital systems.

How M74HC08RM13TR Works and Its Applications in Circuits

The M74HC08RM13TR leverages a two-stage internal circuit, featuring a buffer output stage for enhanced noise immunity and stable outputs under varying load conditions. All input pins are equipped with robust protection circuitry to guard against static discharge and transient overvoltages, supporting design reliability even in ESD-sensitive environments.

Engineers can confidently use the device in high-density PCBs, pulse generation circuits, and digital signal processing units where logic-level timing precision is vital. The device operates across a broad supply voltage range (2 V to 6 V), improving tolerance for system-level voltage variation and enabling use in both legacy and modern mixed-voltage designs.

Electrical Parameters and Reliability Aspects of M74HC08RM13TR

Electrical robustness is central to procurement and engineering decisions. The M74HC08RM13TR supports a range of maximum ratings, including a power dissipation of 500 mW at 65°C, with derating guidelines prescribed for higher operating temperatures. ESD performance is rated for CDM (1 kV), HBM (2 kV), and MM (200 V), supporting survivability in challenging manufacturing and operational environments.

DC and AC performance specifications reflect consistent voltage thresholds and current limits for dependable operation. Balanced rise and fall times (t_PLH ≅ t_PHL) align with applications where pulse fidelity and propagation delay matching are critical, such as high-speed clock distribution and data synchronization networks.
