The FST162244 is a 16-bit bus switch with a 25Ω series resistor. It features low impedance, allowing inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device consists of four 4-bit switches with separate output enable inputs. When OE is low, the switch is on and Port A is connected to Port B. When OE is high, the switch is off and a high impedance state exists between the A and B ports. The FST162244 has an equivalent 25Ω series resistor to reduce signal-reflection noise, eliminating the need for external terminating resistors.
The Fairchild Semiconductor Corporation FST162244 is a 16-bit bus switch designed for high-speed applications. It features four independent 4-bit switches with separate output enable inputs, allowing Port A to connect to Port B when the Output Enable (OE) input is LOW. When OE is HIGH, the device enters a high-impedance state.
