Fairchild Semiconductor FST16861 20-Bit Bus Switch Datasheet
The Fairchild Semiconductor FST16861 is a 20-bit bus switch designed to provide high-speed CMOS TTL-compatible switching between two ports. The device 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. It is organized as either a 10-bit or 20-bit switch, controlled by an OE input that determines the connection state between Port 1A/1B and Port 2A/2B.

Questions answered in these manuals
What is the function of the OE input?
When OE is LOW, the switch is ON and Port 1A is connected to Port 1B, and Port 2A is connected to Port 2B. When OE is HIGH, a high impedance state exists between the A and B Ports.
