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.
