Octal Registered Transceiver with TRI-STATE^® Outputs
General Description
The ’ABT543 octal transceiver contains two sets of D-type
latches for temporary storage of data flowing in either direc-
tion. 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.
