description/ordering information

The SN74CBT6800C is a high-speed TTL-compatible 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

SN74CBT6800C 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 device also precharges the B port to a user-selectable bias

voltage (BIASV) to minimize live-insertion noise.
