The Fairchild Switch FSTU3384 provides 10 bits of 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 generating additional ground bounce noise. Both the A Ports and the B Ports have "undershoot hardened" circuit protection to support an extended input range to 2.0V below ground. FairchildԳ integrated Undershoot Hardened Circuit (UHC®) senses undershoot at the I/Os, and responds by preventing voltage differentials from developing and turning on the switch. The device is organized as two 5-bit switches with separate bus enable (OE#) signals. 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.
