74HC158N,652

Overview

The 74HC158N,652 is a high-speed Si-gate CMOS quad 2-input multiplexer with inverting outputs. It selects four bits of data from two sources controlled by a common select input (S). The enable input (E) is active LOW; when HIGH, all outputs are forced HIGH. It complies with JEDEC standard no. 7A and is pin compatible with low power Schottky TTL. Operating voltage ranges from 2.0 V to 6.0 V. Propagation delay is typically 12 ns at 5 V with 15 pF load. ESD protection exceeds 2000 V (HBM) and 200 V (MM).

Feature Summary

• Quad 2-input multiplexer with inverting data path
• Common data select input controls four independent channels
• Active LOW enable input forces outputs HIGH when inactive
• High ESD protection exceeding 2000 V HBM

Applications

• Moving data between register groups to common output buses
• Function generator for irregular logic implementation
• Implementation of 4-pole, 2-position switching

Procurement Notes

Verify the manufacturer origin, as the datasheet originates from Philips Semiconductors. Confirm the package type matches the 'N' suffix (DIP-16) and temperature range (-40 °C to +125 °C). Ensure compliance with JEDEC standard no. 7A requirements for your specific application environment.

Selection Notes

Select this component for applications requiring inverting multiplexing functions. It serves as the inverted counterpart to the 74HC157. Consider the DIP-16 package for through-hole mounting. Verify supply voltage compatibility within the 2.0 V to 6.0 V range and ensure propagation delay specifications meet system timing requirements.

Part Context

This device belongs to the 74HC series of high-speed CMOS logic devices. It is functionally identical to the 74HC157 but features inverting outputs. The part is specified in compliance with JEDEC standard no. 7A and offers pin compatibility with low power Schottky TTL (LSTTL) standards.

Replacement Considerations

The 74HC157 is the non-inverting equivalent. Other manufacturers produce pin-compatible quad 2-input multiplexers in the 74HC family.
