Abstract
CMOS buffers are described which provide compatibility between a CMOS circuit and ECL circuits. The input buffer includes a comparator referenced to the V.sub.BB potential. This potential is developed on the CMOS chip with bipolar transistors integrally formed during the CMOS processing. The output buffer also utilizes a bipolar transistor and includes overshoot protection circuitry to prevent overshooting in the transition on the output line from a high potential to a low potential.
