The 'ACT16623 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 ( 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 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's 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 -55°C to 125°C. The
74ACT16623 is characterized for operation from -40°C to
