Description

The Fairchild Switch FST32253 is a dual 4:1 high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

When OE is LOW, S0 and S1 connect the A Port to the selected B Port output. When OE is HIGH, the FST32253 is OPEN and a high-impedance state exists between the two ports.

The FST32253 has an equivalent 25Ω series resistor to reduce signal-reflection noise, eliminating the need for external terminating resistors.
