The ON Semiconductor 74FST3125 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 74FST3125 consists of four independent 1−bit 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.
