HD74HC623 Datasheet Octal Bus Transceivers

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC620/HD74HC623 Octal Bus Transceivers (with inverted 3-state outputs) Octal Bus Transceivers (with 3-state.

General Description

This octal bus transceiver is designed for asynchronous two-way munication between data buses.

The control fuction implementation allows for maximum flexibility in timing.

This device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic levels at the enable inputs (GBA and GAB).

Key Features

  • High Speed Operation: tpd (Bus to Bus) = 12 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Enable Inputs GBA L H H L GAB L H L H Operation HD74HC620 B data to A bus A data to B bus Isolation B data to A bus, A data to B bus HD74HC623 B data to A bus A data to B bus Isolation B data.
