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. The outputs are guaranteed to sink 64mA.
The Philips 74LVT543 is an integrated circuit designed as a high-performance BiCMOS product operating at a VCC of 3.3V. It functions as an 8-bit octal transceiver featuring D-type latches for temporary data storage in both directions, combining the capabilities of 74LVT245 and 74LVT373 types into a single device.
