20-Bit Bus Switch With -2V Undershoot Protection

The Fairchild Switch FSTU16861 provides 20-Bits of high- speed CMOS TTL-compatible bus switching. 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 a 10-bit or 20-Bit bus Switch When OE1 is LOW, the Switch is ON and Port 1A is con- nected to Port 1B. When OE2 is LOW, Port 2A is connected to Port 2B. When OEX is HIGH, a high impedance state exists between the A and B Ports. 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. When OE is HIGH, the Switch is OPEN and a high-impedance state exists between the two ports. By Fairchild Semiconductor
