74HC158D,652

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HC158D,652 is a high-speed Si-gate CMOS quad 2-input multiplexer compliant with JEDEC standard no. 7A and pin-compatible with LSTTL. It selects four bits of data from two sources controlled by a common select input (S), presenting inverted outputs. The enable input (E) is active LOW; when HIGH, all outputs are forced HIGH. Operating conditions range from -40°C to +125°C with a supply voltage of 2.0V to 6.0V. Propagation delays reach up to 38ns at 4.5V.

Signal Switches, Multiplexers, Decoders Feature Summary

• Low-power dissipation design

Signal Switches, Multiplexers, Decoders Applications

• Moving data between register groups to common buses
• Function generator applications
• Implementing irregular logic functions

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and temperature range specifications. Confirm availability status directly with authorized distributors as product lifecycles may change. Ensure compliance with RoHS directives and export control regulations relevant to your region before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring a quad multiplexer with inverting outputs. It serves as a direct replacement for the non-inverting 74HC157 where inversion is acceptable. Verify that the SO16 plastic small outline package fits the PCB layout constraints and that the operating voltage range aligns with the system power supply.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74HC family of high-speed CMOS logic products manufactured by Nexperia. These components are designed for general-purpose digital applications, offering performance comparable to low-power Schottky TTL while maintaining lower power consumption. The series supports various industrial and commercial temperature ranges.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74HC157 is functionally identical but provides non-inverting outputs. Verify if the signal inversion requirement matches the application needs before substituting.
