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.

This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging

current will not backflow through the device when it is powered down. The device has isolation during power off.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
