4-Bit Bus Switch With -2V Undershoot Protection

The Fairchild Switch FSTU3125 provides four high-speed CMOS TTL-compatible Bus Switches The low On Resis- tance of the Switch allows inputs to be connected to out- puts without adding propagation delay or generating additional ground bounce noise. The A and B Ports are protected against undershoot to support an extended range to 2.0V below ground. Fairchilds integrated Under- shoot Hardened Circuit (UHC) senses undershoot at the I/O and responds by preventing voltage differentials from developing and turning the Switch on. The device is organized as four 1-bit switches with sepa- rate 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. By Fairchild Semiconductor
