资 源 简 介
The SN74CBT3245C 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 SN74CBT3245C 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 SN74CBT3245C is organized as an 8-bit bus switch with a single output-enable (OE) input. When OE is low, the 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 bus switch is OFF, and the high-impedance state exists between the A and B ports.
This device is fully specified for partial-power-down applications using Ioff.
