74F544
Octal Registered Transceiver
General Description
The 74F544 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 con-
trol of inputting and outputting in either direction of data
flow. The A outputs are guaranteed to sink 24 mA while the
B outputs are rated for 64 mA. The 74F544 inverts data in
both directions.
