Packaging

Type: 16-PDIP (DIP-16), dual-inline through-hole package

Material: Molded epoxy plastic body, copper alloy leadframe, lead-free matte-tin plating for RoHS3 compliance

Size: 0.300 inch body width (7.62 mm); standard 2.54 mm pin pitch; row spacing 7.62 mm; typical body length approximately 19.3 mm

Pin configuration: 16 pins total; 8 channel pins (X0–X7), one common pin (COM), three select pins (A0–A2), enable pin (EN), supply pins (V+, V− or VEE/GND depending on single or dual supply). Refer to the datasheet for the exact pinout and logic truth table.

Thermal characteristics: DIP-16 packages typically exhibit θJA in the 70–100°C/W range in still air; actual thermal performance depends on PCB layout, copper area, and airflow. Follow datasheet guidance for power dissipation and derating.

Electrical properties (package-related and device): On-state resistance 400Ω max; Ton/Toff 500ns; leakage 20pA max; charge injection 1.5pC; CS(off) 3pF; CD(off) 11pF; crosstalk −92dB at 100kHz; ΔRon 4Ω.

Shipment format: Tube packaging for secure transport and storage

Lifecycle

Status: Active and supported by Analog Devices (Maxim Integrated) based on the latest available information; not nearing discontinuation at this time.

Equivalent or alternative models:

- ADG508A (Analog Devices): 8:1 CMOS mux, wide dual-supply up to ±15V; DIP options; typically lower Ron; verify logic levels and specs.

- ADG508F (Analog Devices): 8:1 mux with fault protection; ±15V operation; added protection features; check differences in on resistance and protection circuitry.

- DG508A (Vishay Siliconix): 8:1 mux, ±15V capable; DIP and SOIC; comparable parameters; confirm leakage and Ron.

- CD4051B (Texas Instruments and others): 8-channel analog mux/demux; single-supply up to 20V or dual-supply configurations; DIP package; Ron and leakage differ by vendor and supply voltage.

- MAX4051 (Analog Devices/Maxim): 8:1 mux focused on lower-voltage systems; different voltage limits and Ron; consider if operating below ±5V.

- HI-508A / HS-508A (Renesas/Intersil legacy): 8:1 mux; ±15V support; verify availability and package variants.
