74ABT16543 16-Bit Registered Transceiver with 3-STATE Outputs
October 1993
Revised January 1999
74ABT16543
16-Bit Registered Transceiver with 3-STATE Outputs
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 con-
trol 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.
