20-Bit Bus Switch with -2V Undershoot Protection
FSTU16862 20-Bit Bus Switch with −2V Undershoot Protection May 2002 Revised May 2002 FSTU16862 20-Bit Bus Switch with −2V Undershoot Protection General Description Features The Fairchild Switch FSTU16862 provides 20-bits of high-Undershoot hardened to −2V (A and B Ports) speed CMOS TTL-compatible bus switching. The low On4Ω switch connection between two ports Resistance of the switch allows inputs to be connected to Minimal propagation delay through the switch outputs without adding propagation delay or generating Low l additional ground bounce noise. CC Zero bounce in flow-through mode The device is organized as a 20-bit bus switch. When OE X Control inputs compatible with TTL level is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, a high impedance state existsSee Application Note AN-5008 for details on X between the A and B Ports. The A and B Ports are pro- FSTU - Undershoot Protected Fairchild Switch Family tected against undershoot to support an extended range to 2.0V below ground. Fairchild’s integrated Undershoot Hardened Circuit (UHC) senses undershoot at the I/O and responds by preventing voltage differentials from developing and turning the switch on.
