74HC4051PW-Q100,11

Overview

The Nexperia 74HC4051PW-Q100,11 is an automotive-grade single-pole octal-throw analog switch (SP8T) designed for 8:1 multiplexer and demultiplexer applications. It features three digital select inputs (S0, S1, S2), eight independent bidirectional I/Os (Yn), a common I/O (Z), and an active-low enable input (E). The device operates within a supply voltage range of 2.0 V to 10.0 V and supports an analog input voltage range from -5 V to +5 V. It includes built-in logic level translation to interface 5 V logic with ±5 V analog signals. The component is qualified to AEC-Q100 Grade 1 standards and functions reliably across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• Wide analog input voltage range supporting signals from -5 V to +5 V
• Built-in logic level translation enabling communication between 5 V logic and ±5 V analog signals
• Typical 'break before make' switching action with integrated ESD protection

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the procurement channel provides valid traceability records required for automotive components. Confirm that the delivered units match the exact part number designation to guarantee compliance with AEC-Q100 Grade 1 reliability standards.

Selection Notes

Select this component when designing circuits requiring robust analog signal routing in automotive environments. The TSSOP16 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the wide operating voltage range and high noise immunity when interfacing with mixed-signal systems. Verify thermal dissipation requirements if operating near maximum temperature limits.

Part Context

This component belongs to the Nexperia 74HC4051-Q100 series, which shares functional compatibility with standard 74HC4051 devices but meets stricter automotive reliability criteria. The PW suffix specifically denotes the TSSOP16 plastic thin shrink small outline package variant. Other package options in the family include SO16 and DHVQFN16 configurations.

Replacement Considerations

Direct pin-compatible replacements within the same automotive grade include the 74HCT4051PW-Q100 variant for different logic threshold requirements. Non-automotive equivalents like the standard 74HC4051PW lack the required AEC-Q100 certification and should only be used if automotive qualification is not mandatory.
