HD74HC620/HD74HC623

Octal Bus Transceivers (with inverted 3-state outputs)

Octal Bus Transceivers (with 3-state outputs)

ADE-205-516 (Z)

1st. Edition

Sep. 2000

Description

This octal bus transceiver is designed for asynchronous two-way communication 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).

The enable inputs can be used to disable the device so that the buses are effectively isolated.

The dual-enable configuration gives these devices the capability to store data by simultaneous enabling of

GBA

and GAB. Each output reinforces its input in this transceiver configuration. Thus, when both control

inputs are enabled and all other data sources to the two sets of bus lines are at high impedance, both sets of

bus lines (16 in all) will remain at their last states. The 8-bit codes appearing on the two sets of buses will

be identical for the HD74HC623 or coplementary for the HD74HC620.
