General description

The 74ABT544 high performance BiCMOS device combines low static and dynamic

power dissipation with high speed and high output drive.

The 74ABT544 octal latched transceiver contains two sets of D-type latches for temporary

storage of data flowing in either direction. Separate latch enable (LEAB, LEBA) and output

enable (OEAB, OEBA) inputs are provided for each register to permit independent control

of data transfer in either direction. The outputs are guaranteed to sink 64 mA.
