IDT54/74FCT623T/AT/CT
DESCRIPTION
The FCT623T/AT/CT is a non-inverting octal transceiver
with 3-state bus-driving outputs in both the send and receive
directions. The B bus outputs are capable of sinking 64mA and
sourcing up to 15mA, providing very good capacitive drive
characteristics.
These octal bus transceivers are designed for asynchro-
nous two-way communication between data buses. The control
function implementation allows for maximum flexibility in
timing.
One important feature of the FCT623T/AT/CT is the Power
Down Disable capability. When the GAB and
G
BA inputs are
conditioned to put the device in high-Z state, the I/O ports will
maintain high impedance during power supply ramps and
when V
CC
= 0V. This is a desirable feature in back-plane
applications where it may be necessary to perform “live”
insertion and removal of cards for on-line maintenance. It is
also a benefit in systems with multiple redundancy where one
or more redundant cards may be powered-off.
