About this manual

The Fairchild Switch FST3253 is a dual 4:1 high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch designed to connect inputs to outputs with low on-resistance. It features minimal propagation delay, zero bounce in flow-through mode, and control inputs compatible with TTL levels. When the OE pin is LOW, select inputs S0 and S1 route the A Port signal to one of four B Port outputs; when OE is HIGH, the switch enters a high-impedance state.
