Product Overview FST3126: 4-bit Bus Switch For complete documentation, see the data sheet Product Description The ON Semiconductor 74FST3126 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 1-bit switches with separate Output/Enable (OE) pins. Port A is connected to Port B when OE is high. If OE is low, the switch is high Z.
