8Bit Bus Switch
The ON Semiconductor 74FST3244 is an 8bit, high performance
switch. The device is CMOS TTL compatible when operating between
4 and 5.5 Volts. The device exhibits extremely low R
ON
and adds
nearly zero propagation delay. The device adds no noise or ground
bounce to the system.
The device consists of two 4bit 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.
