FSTU162211 24-Bit Bus Switch with −2V Undershoot Protection and 25Ω Series Resistors in Outputs (Preliminary)
General Description
The Fairchild Switch FSTU162211 provides 24-bits of highspeed 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 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 are protected against undershoot to support an extended range to 2.
