Abstract:
An input receiver that is selectively configured into a burn-in mode and a normal mode, the input receiver comprising:a first transistor having a first terminal connected to a Vdd voltage source, a second terminal, and a third terminal connected to the second terminal;a second transistor having a first terminal connected to the Vdd voltage source, a second terminal connected to the second and third terminals of the first transistor, and a third terminal;a third transistor having a first terminal connected to the second and third terminals of the first transistor, a second terminal for receiving a reference.sub.-- voltage signal, and a third terminal;a fourth transistor having a first terminal connected to the third terminal of the second transistor, a second terminal for receiving an input signal, and a third terminal; anda fifth transistor having a first terminal connected to the third terminal of the third transistor and the third terminal of the fourth transistor, a second terminal for receiving a receiver.sub.-- enable signal, and a third terminal connected to a Vss voltage source;wherein the receiver.sub.-- enable signal is adjusted to a first voltage level when the input receiver is enabled during the burn-in mode and to a second voltage level when the input receiver is enabled during the normal mode, the first voltage level being different from the second voltage level.
