Abstract
Devices for isolating an input from an output are disclosed. For example, a device includes a first p-type metal oxide semiconductor transistor and a first circuit. A source of the first p-type metal oxide semiconductor transistor is connected to an input of the device. The first circuit is for delivering a signal on the input of the device to a gate of the first p-type metal oxide semiconductor transistor when an enable signal is deactivated and for delivering a ground voltage to the gate of the first p-type metal oxide semiconductor transistor when the enable signal is activated.
