The FST34X245 is a 32-bit bus switch with low resistance and minimal propagation delay, suitable for high-speed CMOS TTL-compatible bus switching. It allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.
The Fairchild Semiconductor FST34X245 is a 32-bit bus switch designed for high-speed CMOS TTL-compatible applications. It operates in a standard flow-through mode, connecting Port A to Port B when the OE input is LOW, and presenting a high-impedance state when OE is HIGH. The device features minimal propagation delay and low quiescent current.
