DESCRIPTION
The 74ABT623 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT623 device is an octal transceiver featuring non–inverting
3-State bus compatible outputs in both send and receive directions.
The 74ABT623 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 (OEBA and OEAB). The Enable inputs can be used to disable
the device so that the buses are effectively isolated.
