74AHC157PW-Q100J

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC157PW-Q100J is a high-speed Si-gate CMOS quad 2-input multiplexer. It selects 4 bits of data from two sources under the control of a common data select input (S). The enable input (E) is active LOW; when HIGH, all outputs are forced LOW. It operates with a supply voltage range of 2.0 V to 5.5 V and features balanced propagation delays. The device is specified for ambient temperatures from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1
• All inputs have Schmitt-trigger action
• Inputs accept voltages higher than VCC
• Multiple input enable for easy expansion

Signal Switches, Multiplexers, Decoders Applications

• Moving data from two groups of registers to four common output buses
• Implementing highly irregular logic by generating functions of two variables
• Memory chip select decoding

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'J' against the manufacturer's current documentation to confirm package type and temperature grade. Confirm that the TSSOP16 package variant matches the design requirements. Ensure compliance with AEC-Q100 Grade 1 specifications for automotive deployment. Check for any recent Product Change Notifications affecting pinout or electrical characteristics.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring high-speed data routing between two register groups. The AHC series offers low power consumption and direct interface capabilities. Verify that the input voltage levels match the source devices, as the AHC variant operates with CMOS input levels. Ensure the operating temperature range meets the environmental constraints of the target system.

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 family includes variants such as the 74AHCT157-Q100, which operates with TTL input levels. The device complies with JEDEC standard no. 7A.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AHC157PW,118 is a non-automotive qualified equivalent in the same TSSOP16 package. For TTL-compatible input levels, the 74AHCT157PW-Q100 serves as a functional alternative within the automotive-grade family.
