Abstract
An input circuit designed for a semiconductor device. A first input buffer (14) receives a control signal EN, an input signal IN, and a reference signal VREF, for producing a first output signal OUT.sub.1 in response the control signal and a difference between the input signal and the reference signal. A second input buffer (16) receives the control signal and the input signal, for producing a second output signal OUT.sub.2 in response to the control signal and the input signal. A control circuit (22) produces the control signal, in response to a predetermined output state.
