Octal Bus Transceivers (with 3-state outputs)

Description

This octal bus transceiver is designed for asynchronous two-way communication between data buses. The control

function 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 HD74HCT623 or

complementary for the HD74HCT620.

Features
