74AHC157PW,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC157PW,118 is a quad 2-input multiplexer housed in a TSSOP16 (SOT403-1) package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. Propagation delays vary by load capacitance; at 50 pF, delays are 16.5 ns maximum at 3.0 V and 10.5 ns maximum at 5.0 V. The device features balanced propagation delays, Schmitt-trigger inputs, and ESD protection exceeding 2000 V (HBM).

Signal Switches, Multiplexers, Decoders Feature Summary

• Quad 2-input multiplexer architecture with common data select and active LOW enable.
• Schmitt-trigger action on all inputs for tolerance of slower rise and fall times.
• Inputs accept voltages higher than the supply voltage (VCC).
• Multiple input enable capability facilitates easy circuit expansion.

Signal Switches, Multiplexers, Decoders Applications

• Moving data between two groups of registers to four common output buses.
• Memory chip select decoding.
• Function generation implementing logic functions of two variables.
• Logic implementation of a 4-pole, 2-position switch.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when high-speed switching is required alongside CMOS input level compatibility. The AHC series offers lower power consumption compared to standard HC logic while maintaining speed. Ensure the design accommodates the TSSOP16 thermal derating characteristics if operating near the upper temperature limits.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AHC/AHCT157 family of quad 2-input multiplexers. It is pin-compatible with Low Power Schottky TTL (LSTTL) devices. The 'PW' designation specifically identifies the plastic thin shrink small outline package (TSSOP16), distinguishing it from SOIC or QFN variants within the same logical family.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AHCT157PW,118 is a direct functional replacement within the same package, differing only in input threshold levels (TTL compatible). Other 74AHC157 variants exist in different packages such as SOIC-16 (74AHC157D) or DHVQFN16 (74AHC157BQ).
