Renesas Electronics Corporation Buffers, Drivers, Receivers, Transceivers 74FCT543ATQG8

The 74FCT543ATQG8 is a fast CMOS octal latched transceiver designed for industrial applications, operating within a temperature range of -40¬8C to +85¬8C. It features low input and output leakage currents, with a maximum of 1¬µA, and provides true TTL input and output compatibility, with typical output high voltage (VOH) of 3.3V and output low voltage (VOL) of 0.3V. The device supports high drive outputs, capable of sourcing -15mA and sinking 64mA, making it suitable for various data transmission needs. This transceiver includes two sets of eight D-type latches with separate controls for data flow in both directions (A to B and B to A), allowing for flexible data management. The power-off disable outputs enable "live insertion," enhancing usability in dynamic environments. The 74FCT543ATQG8 is available in a quarter-size small outline package (QSOP), facilitating integration into compact designs. It meets or exceeds JEDEC standard 18 specifications, ensuring reliability and performance in demanding applications.
