The FST16211 24-Bit Bus Switch is a high-speed CMOS TTL-compatible bus switch from Fairchild Semiconductor Corporation. The switch has a low on-resistance, 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 Fairchild FST16211 is a 24-bit bus switch designed to connect inputs to outputs with minimal propagation delay and zero bounce. The device operates as two independent 12-bit switches or one single 24-bit switch, controlled by an Output Enable (OE) input that connects Port A to Port B when LOW.
