The SN74CBT3305C 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 device 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 SN74CBT3305C is organized as two 1-bit bus switches with separate output-enable (1OE, 2OE) inputs. It
can be used as two 1-bit bus switches or as one 2-bit bus switch. When OE is high, the associated 1-bit bus
switch is ON, and the A port is conncected to the B port, allowing bidirectional data flow between ports. When
OE is low, the associated 1-bit bus switch is OFF, and the high-impedance state exists between the A and B
ports.
