74HCT4051PW,112

Analog Switches, Multiplexers, Demultiplexers Overview

The Nexperia 74HCT4051PW,112 is an 8-channel analog multiplexer/demultiplexer housed in a TSSOP-16 package. It operates with a VCC supply voltage range of 4.5 V to 5.5 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), a common I/O (Z), and an active LOW enable input (E). Key electrical parameters include a maximum ON resistance of 180 Ω at VCC=4.5V/VEE=0V, propagation delay up to 12 ns, turn-on time up to 55 ns, and turn-off time up to 45 ns. It complies with JEDEC standards and offers ESD protection exceeding 2000 V HBM.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix ',112' against official Nexperia documentation to confirm specific reel packaging or tape-and-reel specifications. Ensure the component matches the TSSOP-16 form factor and that the datasheet revision aligns with current manufacturing standards. Cross-reference the part number with authorized distributors to validate authenticity and traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when 5 V CMOS logic control is required to switch analog signals within a ±5 V range. The TSSOP-16 package is suitable for surface-mount applications requiring a compact footprint. Consider the maximum ON resistance and leakage currents if designing for high-precision analog paths or low-power consumption scenarios.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the 74HCT family of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other industry-standard 8:1 analog switches but is specifically optimized for 5 V logic operation. The PW suffix indicates the plastic thin shrink small outline package variant.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible alternatives include the 74HC4051PW for broader voltage ranges or the 74HCT4051BQ in a DHVQFN package for space-constrained designs. Verify switching speed and ON resistance characteristics match application requirements when substituting.
