General Description
The 74FR543 octal 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. Both the A and B outputs will source 15 mA and sink 64 mA.

Features
