74ABT543A

74ABT543A Octal latched transceiver with dual enable; 3-state Rev. 5 — 3 November 2011 Product data sheet 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. 2.
