SN74CBTLV16800 具有预充电输出的低电压 20 位 FET 总线开关

The SN74CBTLV16800 provides 20 bits of high-speed bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device also precharges the B port to a user-selectable bias voltage (BIASV) to minimize live-insertion noise.

The device is organized as dual 10-bit bus switches with separate output-enable (OE\) inputs. It can be used as two 10-bit bus switches or one 20-bit bus switch. When OE\ is low, the associated 10-bit bus switch is on, and port A is connected to port B. When OE\ is high, the switch is open, the high-impedance state exists between the two ports, and port B is precharged to BIASV through the equivalent of a 10-k resistor.

This device is fully specified for partial-power-down applications using Ioff
