HD74HC444 - Quad Tridirectional Bus Transceiver

This page provides the datasheet information for the HD74HC444, a member of the HD74HC442 Quad Tridirectional Bus Transceiver family.

Datasheet Summary

Description

These bus transceivers are designed for a synchronous three-way communication between four-line data buses.

They give the designer a choice of selecting inverting, noninverting or a combination of inverting and noninverting data paths with 3-state outputs.

Features

  • High Speed Operation.
  • High Output Current: Fanout of 15 LSTTL Loads.
  • Wide Operating Voltage: VCC = 2 to 6 V.
  • Low Input Current: 1.

They give the designer a choice of selecting inverting, noninverting or a combination of inverting and noninverting data paths with 3-state outputs. The S0 and S1 inputs select the bus from which data are to be transferred. The G inputs enable the bus or buses to which data are to be transferred.
