Product description
4-Bit Bus Switch
The Fairchild Switch FST3125 provides four high-speed CMOS TTL-compatible bus switches. 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 four 1-bit switches with separate OE inputs. When OE is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.
Features
* 4ohm switch connection between two ports.
* Minimal propagation delay through the switch.
* Low Icc.
* Zero bounce in flow-through mode.
* Control inputs compatible with TTL level.
