HD74HC443 - Quad. Tridirectional Bus Transceiver

Download the HD74HC443 datasheet PDF. This datasheet also covers the HD74HC442 variant, as both devices belong to the same quad. tridirectional bus transceiver family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

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

Tridirectional Bus Transceiver (with inverted 3-state outputs) Quad Tridirectional Bus Transceiver (with noninverted/inverted 3-state outputs) REJ03D0627-0200 (Previous ADE-205-506) Rev.2.00 Mar 30, 2006 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. 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.
