Dual 1-of-4 FET multiplexer/demultiplexer

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.

The CBT3253 is characterized for operation from ‑40 °C to +85 °C.
