The 'ABT16543 16-bit registered transceivers contain two sets of D-type latches for temporary storage of data flowing in either direction. The 'ABT16543 can be used as two 8-bit transceivers or one 16-bit transceiver. Separate latch-enable ( or) and output-enable ( or ) inputs are provided for each register to permit independent control in either direction of data flow.

The A-to-B enable () input must be low to enter data from A or to output data from B. If is low and is low, the A-to-B latches are transparent; a subsequent low-to-high transition of puts the A latches in the storage mode. With and both low, the 3-state B outputs are active and reflect the data present at the output of the A latches. Data flow from B to A is similar but requires using the,, and inputs.

To ensure the high-impedance state during power up or power down, should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABT16543 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT16543 is characterized for operation from -40°C to 85°C.
