74AHC157D-Q100J

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC157D-Q100J is a quad 2-input multiplexer housed in an SO16 (SOT109-1) plastic small outline package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features balanced propagation delays, Schmitt-trigger inputs, and overvoltage tolerant inputs that accept voltages higher than VCC. It includes multiple input enable capabilities for easy expansion and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Qualified to AEC-Q100 Grade 1 standards, it is suitable for automotive applications.

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
• Memory chip select decoding
• Function generator implementation

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm exact packaging details, as datasheets may list standard suffixes like 'D' or 'PW'. Confirm the package type corresponds to SOT109-1 (SO16) rather than TSSOP or DHVQFN variants. Ensure the component meets the required AEC-Q100 Grade 1 qualification for your specific automotive application environment.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad 2-input multiplexer with high-speed CMOS performance and automotive reliability is required. It is appropriate for mixed-voltage environments due to overvoltage tolerant inputs. Consider the SO16 package dimensions if board space allows, and verify that the 2.0 V to 5.5 V operating range aligns with your system's power supply specifications.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AHC/AHCT157-Q100 family of quad 2-input multiplexers manufactured by Nexperia. These devices are pin-compatible with Low Power Schottky TTL (LSTTL) and comply with JEDEC standard no. 7A. The family includes variants such as 74AHCT157D-Q100J, which differ primarily in input logic level compatibility (CMOS vs. TTL).

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AHCT157D-Q100J serves as a functional alternative within the same package, differing only in input logic level requirements (TTL compatible). Other package options include 74AHC157PW-Q100J (TSSOP16) and 74AHC157BQ-Q100J (DHVQFN16), which require footprint adjustments.
