1. General description

The CBT3253 is a dual 1-of-4 high-speed TTL-compatible FET multiplexer/demultiplexer. 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 select control inputs (S0, S1) can select the data path, when both output enable inputs (1OE,

2OE) are LOW. When nOE is HIGH, the switch terminals are in the high impedance OFF-state,

independent of S0 and S1.

2. Features and benefits
