摘要:
An integrated circuit device includes a pad adapted to receive a signal from an internal or external driver, and an input buffer circuit including an input terminal coupled to the pad. The input buffer circuit includes a pass transistor having a control terminal, a first conduction terminal connected to the pad, and a second conduction terminal connected to a first voltage. The input buffer circuit also includes a latch having a terminal electrically coupled to the control terminal of the pass transistor. The input buffer circuit further includes circuitry coupled to the latch, the circuitry including a feedback transistor having a control terminal electrically coupled to the pad, a first conduction terminal electrically coupled to a second voltage, and a second conduction terminal coupled to the latch.
