description/ordering information

allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B ports of the

SN74CBT3384C 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 SN74CBT3384C is organized as two 5-bit bus switches with separate output-enable (1OE, 2OE) inputs.

It can be used as two 5-bit bus switches or as one 10-bit bus switch. When OE is low, the associated 5-bit bus

switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When

OE is high, the associated 5-bit bus switch is OFF, and the high-impedance state exists between the A and B

ports.
