The Fairchild Switch FSTU162211 provides 24-bits of highspeed CMOS TTL-compatible bus switching. The low OnResistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating
additional ground bounce noise.
The FSTU162211 is organized as a 12-bit or 24-bit bus switch.When OE1 is LOW, the switch is ON and Port 1A is connected
to Port 1B. When OE2 is LOW, Port 2A is connected to Port 2B. The A and B Ports of FSTU162211 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 FSTU162211 has equivalent 25 series resistors to reduce signal-reflection noise, eliminating the need for external terminating resistors
