The 74ABT543A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT543A Octal Registered 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 64mA.
