Abstract
An integrated circuitincludes a receiver circuitfor receiving an input signal PAD and converting this to an output signal OUT. Conduction path circuitrycouples an inputto a first node. Buffer circuitryis coupled between the first nodeand an outputcarrying the output signal Out. The conduction path circuitry comprises a first PMOS transistorand a second PMOS transistorconnected between the inputand the first node. A first NMOS transistoris connected between the inputand the first node. The gate of the second PMOS transistoris coupled to the outputto directly receive the output signal and thereby achieve rapid cut off of the charging of the nodewhen the input voltage rises beyond a certain level which switches the buffer circuitry
