The SN74CBT16811C 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 SN74CBT16811C 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.
The SN74CBT16811C is organized as two 12-bit bus switches with separate output-enable (1OE, 2OE) inputs. It can be used as two 12-bit bus switches or as one 24-bit bus switch. When OE is low, the associated 12-bit bus switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports.
