74LVT543 Overview
The 74LVT543 is a high-performance BiCMOS product designed for VCC operation at 3.3V. This device 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.
