Low-Voltage 20-Bit FET Bus Switch With Precharged Outputs

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. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
