The Fairchild Switch FST16211 is a device that provides 24-bits of high-speed CMOS TTL-compatible bus switching. It features a low on resistance switch, which allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device is organized as a 12-bit or 24-bit bus switch. When OE1 is low, the switch is on and Port 1A is connected to Port 1B. When OE2 is low, Port 2A is connected to Port 2B. When OE1/2 is high, a high impedance state exists between the A and B ports. The device has features such as a 4Ω switch connection, minimal propagation delay, low lCC, zero bounce in flow-through mode, and control inputs compatible with TTL level.
