Description

The Fairchild Switch FST162245 provides 16-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 FST162245 is organized as a 16-bit switch. There are 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 the A and B Ports. The FST162245 has an equivalent 25Ω series resistors to reduce signal-reflection noise, eliminating the need for external terminating resistors.
