The FST162245 is a 16-bit bus switch with high-speed CMOS TTL compatibility. 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 consists of two 8-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 Port A and Port B. The FST162245 has equivalent 25-ohm series resistors to reduce signal-reflection noise, eliminating the need for external terminating resistors.
The Fairchild Semiconductor FST162245 is a 16-bit bus switch designed for high-speed CMOS TTL-compatible applications. It consists of two 8-bit switches with separate output enable inputs, allowing Port A to be connected to Port B when the Output Enable (OE) input is LOW. When OE is HIGH, the switch enters a high-impedance state.
The device features an equivalent 25Ω series resistor in the outputs to reduce signal-reflection noise, eliminating the need for external terminating resistors. It is available in a 48-Lead Thin Shrink Small Outline Package (TSSOP).
