The SN74CBT16210C 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 SN74CBT16210C 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 SN74CBT16210C is organized as two 10-bit bus switches with separate output-enable (1OE, 2OE) inputs. It can be used as two 10-bit bus switches or as one 20-bit bus switch. When OE is low, the associated 10-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 10-bit bus switch is OFF, and the high-impedance state exists between the A and B ports.
