Description

The Fairchild Switch FSTU3125 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 A and B Ports of FSTU3125 are protected against undershoot to support an extended range to 2.0V below ground. Fairchild's integrated Undershoot Hardened Circuit (UHCTM) senses undershoot at the I/O and responds by preventing voltage differentials from developing and turning the switch on.

The FSTU3125 is organized as four 1-bit switches with separate OE inputs. When OE is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports
