Abstract
A transmission gate circuit with high impedance during power off conditions, which includes a first transistor coupled between a first terminal and a second terminal and a second transistor coupled between the first terminal and the second terminal. Also included is a control circuit configured to monitor voltages on the first terminal and on a first voltage source, the control circuit configured to couple the gates of the first and second transistors to a voltage that will keep the first and second transistors off during power off conditions.
