Product Overview FST3125: 4-Bit Bus Switch For complete documentation, see the data sheet Product Description The ON Semiconductor FST3125 is a quad, high performance switch. The device is CMOS TTL compatible when operating between 4 and 5.5 Volts. The device exhibits extremely low RON and adds nearly zero propagation delay. The device adds no noise or ground bounce to the system. The device consists of four independent 1bit switches with separate Output Enable (OE) pins. Port A is connected to Port B when OE is low. If OE is high, the switch is high Z.
