General Description

/ordering information The SN74CBT3345C is a high-speed TTL-patible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay.

Active Undershoot-Protection Circuitry on the A and B ports of the SN74CBT3345C 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 SN74CBT3345C is organized as an 8-bit bus switch with two output-enable (OE, OE) inputs.
