74HC258 datasheet


The 74HC258 is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). The 74HC258 is specified in compliance with JEDEC standard no. 7A.

The 74HC258 has four identical 2-input multiplexers with 3-state outputs, which select 4 bits of data from two sources and is controlled by a common data select input (S).


* 3-state outputs interface directly with system bus

* Low-power dissipation

* Inverting data path

* Complies with JEDEC standard no. 7A

* ESD protection:
  – HBM JESD22-A114E exceeds 2000 V
  – MM JESD22-A115-A exceeds 200 V

* Multiple package options

* Specified from−40°Cto+85°C and from−40°C to +125°C.
