74HC4051PW,118

Overview

The Nexperia 74HC4051PW,118 is an 8-channel analog multiplexer/demultiplexer housed in a TSSOP16 package. It operates with a supply voltage range of 2.0 V to 10.0 V and supports dual supplies from -5 V to +5 V. The device features three digital select inputs (S0, S1, S2), eight independent I/Os (Yn), and a common I/O (Z). Key electrical parameters include a maximum on-resistance of 180 Ω at 4.5 V, propagation delay up to 90 ns, and turn-on/turn-off times reaching 59 ns and 49 ns respectively. It complies with JEDEC standards and offers high noise immunity.

Feature Summary

• Single-pole octal-throw analog switch configuration for 8:1 multiplexing
• Wide analog input voltage range supporting signals from -5 V to +5 V
• Built-in ESD protection exceeding 2000 V HBM and 1000 V CDM
• Logic level translation capability between 5 V logic and ±5 V analog signals

Applications

• Analog multiplexing and demultiplexing
• Digital multiplexing and demultiplexing
• Signal gating

Selection Notes

Select this component when an 8-channel analog switch is required within a TSSOP16 footprint. Ensure the application voltage does not exceed the 10 V absolute maximum rating. Consider the 74HCT4051 variant if TTL-compatible input thresholds are necessary for 5 V logic systems instead of standard CMOS levels.

Part Context

This part belongs to the 74HC/HCT4051 family of single-pole octal-throw switches. It shares functional compatibility with other variants like the SO16 packaged 74HC4051D but differs in physical dimensions and thermal characteristics due to the thin shrink small outline package design.

Replacement Considerations

Direct pin-compatible replacements include the 74HC4051D (SO16) and 74HC4051BQ (DHVQFN16). Verify that the substitute package meets the mechanical constraints of the existing PCB layout.
