Abstract

An off-chip receiver circuit for interfacing an integrated circuit of a 2.5 Volt CMOS technology to a 3.3 Volt LVTTL bus. The off-chip receiver includes protection circuitry for preventing overstressing of the gate oxide caused by undershoot/overshoot peaks of -1 volt to 6 volts on the input.
