The FST16861 is a 20-bit high-speed CMOS TTL-compatible bus switch with low switch resistance, which allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. It can be used as a 10-bit or 20-bit bus switch.
The Fairchild Semiconductor FST16861 is a 20-bit bus switch designed to provide high-speed CMOS TTL-compatible switching between two ports. It features minimal propagation delay and zero bounce in flow-through mode, making it suitable for connecting inputs to outputs without adding significant delay or ground bounce noise. The device is organized as either a 10-bit or 20-bit switch, controlled by enable inputs that connect Port 1A to Port 1B and Port 2A to Port 2B when enabled.
