Product data sheet
1. 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.
