74HC4051BQ,115

Overview

The Nexperia 74HC4051BQ,115 is an 8-channel analog multiplexer/demultiplexer housed in a DHVQFN16 package (SOT763-1). It operates with 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. The device features three digital select inputs (S0, S1, S2), eight independent I/Os (Yn), a common I/O (Z), and an active-low enable input (E). Key electrical parameters include a maximum ON resistance of 180 Ω at 4.5 V supply, propagation delay up to 90 ns, and power dissipation of 500 mW. It functions within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Supports bidirectional analog or digital signal routing between one common port and eight independent ports
• Provides logic level translation capabilities for interfacing 5 V logic with ±5 V analog signals
• Includes built-in ESD protection exceeding 2000 V HBM and 1000 V CDM standards

Applications

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

Selection Notes

Select this component when space-constrained designs require a leadless thermal-enhanced package. The DHVQFN16 form factor offers a compact footprint suitable for high-density PCB layouts while maintaining robust thermal performance for continuous operation across the full industrial temperature range.

Part Context

This part belongs to the 74HC4051 series of single-pole octal-throw analog switches. It is functionally compatible with other variants in the family, such as the SO16 (74HC4051D) and TSSOP16 (74HC4051PW) packages, allowing for design flexibility based on manufacturing preferences without altering circuit functionality.

Replacement Considerations

Direct pin-compatible replacements include 74HC4051D, 74HC4051PW, and 74HCT4051BQ. Ensure the substitute matches the required operating temperature range and package dimensions if mechanical constraints are strict.
