The 74AC16623 is a 16-bit transceiver designed for asynchronous communication between data buses. The control function implementation allows for maximum flexibility in timing.

The 74AC16623 can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon 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 simultaneous enabling of OEBA and OEAB. 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, the bus lines will remain at their last states.

The 74AC16623 is packaged in TI's shrink small-outline package (DL), which provides twice the I/O pin count and  unctionality of standard small-outline packages in the same printed-circuit-board area.

The 74AC16623 is characterized for operation from 40°C to 85°C.
