M54HCT158 - QUAD 2 CHANNEL MULTIPLEXER

Download the M54HCT158 datasheet PDF. This datasheet also covers the M54HCT157 variant, as both devices belong to the same quad 2 channel multiplexer family and are provided as variant models within a single manufacturer datasheet.

General Description

The M54/74HCT157 and the M54/74HCT158 are high speed CMOS QUAD 2-CHANNEL MULTIPLEXERs fabricated with silicon gate C2MOS technology.

They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
