The FST16862 is a 20-bit high-speed CMOS TTL-compatible bus switch with low on resistance and minimal propagation delay. It allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device is organized as a 20-bit bus switch. When OEX is low, the switch is on and Port A is connected to Port B. When OEX is high, a high impedance state exists between Port A and Port B.
The Fairchild Semiconductor FST16862 is a 20-bit bus switch designed to provide high-speed CMOS TTL-compatible switching between two ports. It features low on-resistance to minimize propagation delay and ground bounce noise, and operates in a zero-bounce flow-through mode. The device is organized as a 20-bit switch where a low OE input connects Port A to Port B, while a high OE input places the ports in a high-impedance state.
