74AHCT157PW-Q100J

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHCT157PW-Q100J is a quad 2-input multiplexer manufactured using high-speed Si-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device features balanced propagation delays, Schmitt-trigger action on all inputs, and an active LOW enable input that forces outputs LOW when inactive. Qualified under AEC-Q100 Grade 1 standards, it supports ambient temperatures from -40 °C to +125 °C and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Signal Switches, Multiplexers, Decoders Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• Operates with TTL input levels for direct interface with 5 V logic
• All inputs feature Schmitt-trigger action for noise immunity
• Inputs accept voltages higher than the supply voltage (VCC)

Signal Switches, Multiplexers, Decoders Applications

• Moving data between two groups of registers to four common output buses
• Memory chip select decoding
• Function generation implementing irregular logic functions

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm packaging details, as datasheets may list standard variants without this suffix. Ensure the application environment strictly adheres to the specified 4.5 V to 5.5 V supply voltage range and temperature limits defined in the recommended operating conditions.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-compatible inputs are required for 5 V systems. The AHCT series is distinct from the AHC series by its ability to interface directly with TTL logic levels. Verify that the TSSOP16 package meets the board space constraints and thermal requirements for the intended operating temperature range up to +125 °C.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AHC/AHCT157-Q100 family of quad 2-input multiplexers. It is pin-compatible with Low Power Schottky TTL (LSTTL) devices. The product line includes variants with different packages such as SO16 and DHVQFN16, and logic families including AHC and AHCT, all sharing the same core multiplexer functionality.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AHC157PW-Q100J serves as a CMOS-level compatible alternative within the same package. Other package options include the 74AHCT157D-Q100 (SO16) and 74AHCT157BQ-Q100 (DHVQFN16). Cross-referencing with other manufacturers' 74AHCT157 equivalents requires verification of pinout and electrical specifications.
