ABSTRACT:
A method and apparatus for transmitting signals between electronic circuits having different power supplies. In one preferred embodiment, an input buffer is provided to a first circuit that uses a first power supply for receiving input signals from a second circuit that uses a second power supply. The input buffer translates the input signal from the second signal level used in the second circuit so as to be compatible with the first circuit. Also, in the preferred embodiment, the input buffer includes a reference voltage generator that generates the reference signal at a level corresponding to a logical threshold or "trip point" voltage level between the high and low voltage states of the second power supply. In particular, the voltage threshold is dynamically self-adjusted in proportion to the second power supply voltage level used in the second circuit.
