VCC Isolation and VCC Disconnect

In conjunction with the dyncamic pull-downs, the LXC family has introduced the new VCC Disconnect feature. This feature is an improvement to the already existing VCC Isolation and Partial Power Down features. As illustrated in Figure 3-1, the VCC Disconnect feature will discharge any charge at the supply pin allowing the device to go into a disabled state whenever the supply node is floated rather than driven to ground.

This feature is beneficial for applications where the translation device is connected to a power source through a load switch. Refer to the Feature Description section of the data sheet for more info on the VCC Disconnect feature.
