FST3126 4-Bit Bus Switch
General Description
The Fairchild Switch FST3126 provides four high-speed CMOS TTL-compatible bus switches. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device is organized as four 1-bit switches with separate OE inputs. When OE is HIGH, the switch is ON and Port A is connected to Port B. When OE is

Product Preview 4-Bit Bus Switch
The ON Semiconductor FST3126 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.
