74ABT543A中文资料安世数据手册PDF规格书

1. General description

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

64 mA.
