DM74AS158 - Quad 1 of 2 Line Data Selector/Multiplexer

This page provides the datasheet information for the DM74AS158, a member of the DM74AS157 Quad 1 of 2 Line Data Selector/Multiplexer family.

Datasheet Summary

Description

These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four output gates.

A separate STROBE input is provided.

A 4-bit word is selected from one of two sources and is routed to the four outputs.

Features

  • s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range s Advanced oxide-isolated, ion-implanted Schottky TTL process s Functionally and pin for pin compatible with Schottky, low power Schottky, and advanced low power Schottky TTL counterpart s Improved AC performance over Schottky, low power Schottky, and advanced low power Schottky counterparts s Expand any data input point s Multiplex dua.

A separate STROBE input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. The AS157 presents true data whereas the AS158 presents inverted data to minimize propagation delay time.
