Description

The SN74CBT16211C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (r_on), allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B ports of the SN74CBT16211C 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 SN74CBT16211C 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. When OE\ is high, the associated 12-bit bus switch is OFF, and the high-impedance state exists between the A and B ports.
