Abstract
A transmission gate includes a first P-type transistor and a second P-type transistor coupled in series between a first signal node and an internal node. The transmission gate is enabled by turning on the first P-type transistor and the second P-type transistor to communicate signals between the first signal node and the internal node. The transmission gate is disabled by turning off the first P-type transistor and the second P-type transistor to stop communicating signals between the first signal node and the internal node. While the transmission gate is disabled, a third P-type transistor having a first current electrode coupled to a circuit node between the first and second P-type transistors and a control electrode coupled to the first signal node is used to track voltage of the first signal node and, in response to the tracking, control a voltage level at the circuit node to limit a gate-to-source voltage of the first P-type transistor.
