Octal Registered Transceiver
General Description
The ’F544 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 The
A outputs are guaranteed to sink 24 mA (20 mA Mil) while
the B outputs are rated for 64 mA (48 mA Mil) The ’F544
inverts data in both directions
