description
The 鈥橝CT16623 are 16-bit transceivers designed
for asynchronous two-way communication between
data buses. The control-function implementation
allows for maximum flexibility in timing.
These devices can be used as two 8-bit
transceivers or one 16-bit transceiver. They allow
data transmission from the A bus to the B bus or
from the B bus to the A bus, depending on the logic
level at the output-enable (OEBA and OEAB)
inputs. The output-enable inputs can be used to
disable the device so that the buses are effectively
isolated.

The dual-enable configuration gives the bus transceiver the capability to store data by simultaneously enabling
OEBA and OEAB. Each output reinforces its input in this transceiver configuration. When both control inputs
are enabled and all other data sources to the two sets of bus lines are at high impedance, the bus lines remain
at their last states.
The 74ACT16623 is packaged in TI鈥檚 shrink small-outline package, which provides twice the functionality of
standard small-outline packages in the same printed-circuit-board area.
The 54ACT16623 is characterized for operation over the full military temperature range of 鈥?5擄C to 125擄C. The
74ACT16623 is characterized for operation from 鈥?0擄C to 85擄C.
