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.
