The Fairchild Switch FST162861 provides 20-Bits of highspeed CMOS TTL-compatible bus switching. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device is organized as a 10-bit or 20-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 OEX is HIGH, a high impedance state exists between the A and B ports. The FST162861 has an
