SN74CBT6845C 具有预充电输出和 -2V 下冲保护的 8 位 FET 5V 总线开关

The SN74CBT6845C 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 SN74CBT6845C 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 SN74CBT6845C is an 8-bit bus switch with a single output-enable (OE\) input. When OE\ is low, the 8-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 8-bit bus switch is OFF, and a high-impedance state exists between the A and B ports
