Fairchild Semiconductor FST3125 Quad Bus Switch Datasheet
The Fairchild Semiconductor FST3125 is a quad bus switch device providing four high-speed CMOS TTL-compatible switches. It features low on-resistance and zero bounce in flow-through mode, with control inputs compatible with TTL levels. The device allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.
