QS74FCT543T Overview
The QSFCT543T and QSFCT2543T are 8-bit highspeed CMOS TTL-patible latched bus transceivers with three-state outputs that are ideal for driving high capacitance loads such as memory and address buses. The 2543 devices are 25Ω resistor output versions useful for driving transmission lines and reducing system noise. The 2543 series parts can replace the 543 series to reduce noise in an existing design.
