The FST32245 is an octal bus switch with a 25Ω series resistor. The switch has a low On Resistance, allowing inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device is organized as an 8-bit switch. 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. The FST32245 has an equivalent 25Ω series resistor to reduce signal-reflection noise, eliminating the need for external terminating resistors.
