The ON Semiconductor 74FST3244 is an 8−bit, 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 two 4−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.
