DESCRIPTION/ORDERING INFORMATION
The SN74CBT3253C is a high-speed TTL-compatible FET multiplexer/demultiplexer with low ON-state
resistance (ron), allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B
ports of the SN74CBT3253C provides protection for undershoot up to –2 V by sensing an undershoot event and
ensuring that the switch remains in the proper OFF state.
The SN74CBT3253C is organized as two 1-of-4 multiplexer/demultiplexers with separate output-enable (1OE,
2OE) inputs. The select (S0, S1) inputs control the data path of each multiplexer/demultiplexer. When OE is low,
the associated multiplexer/demultiplexer is enabled, and the A port is connected to the B port, allowing
bidirectional data flow between ports. When OE is high, the associated multiplexer/demultiplexer is disabled, and
a high-impedance state exists between the A and B ports.
