General Description
The ABT16543 16-bit transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate Latch Enable and Output Enable inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow. Each byte has separate control inputs, which can be shorted together for full 16-bit operation.
