Overview
The Nexperia 74HC4351PWJ is an 8-channel analog multiplexer/demultiplexer with address latches, housed in a TSSOP20 (SOT360-1) package. It operates as a single-pole octal-throw switch with three digital select inputs (S0-S2), eight independent I/Os (Yn), and one common I/O (Z). The device supports dual supplies VCC and VEE, enabling an analog input voltage range from -5 V to +5 V. Static characteristics include low ON resistance, typically 80 Ω at VCC-VEE=4.5 V, and high OFF-state isolation. ESD protection exceeds 2000 V HBM and 1000 V CDM. Operating temperature ranges from -40 °C to +125 °C.
Feature Summary
- Integrated address latching for stable channel selection
- Wide analog signal handling capability across dual supply rails
- Built-in 'break before make' switching action
- High electrostatic discharge robustness
Applications
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current product data sheet to confirm package type and temperature grade. Confirm availability status directly with authorized distributors or the manufacturer, as production status may change. Ensure the selected variant matches the required logic family specifications for the target application design.
Selection Notes
Select the 74HC4351 variant when CMOS logic compatibility and wide analog voltage swing are required. Verify that the supply voltage differential (VCC minus VEE) meets the minimum threshold for acceptable ON resistance linearity. Consider the 74HCT4351 if TTL-compatible input levels are necessary instead of standard CMOS thresholds.
Part Context
This component belongs to the 74HC/HCT series of logic ICs manufactured by Nexperia. It utilizes a plastic thin shrink small outline package (TSSOP20) designated as SOT360-1. The part is designed for surface-mount assembly and complies with JEDEC standard no. 7A for operating conditions.
Replacement Considerations
The 74HCT4351PWJ serves as a compatible alternative within the same package, offering TTL-compatible input thresholds while maintaining identical pinout and functional behavior.
