ABSTRACT:
A buffer circuit is provided for buffering an input clock signal having TTL voltage levels to provide an output clock signal having MOS voltage levels. A reference voltage portion provides an accurate bias voltage to a first node. A voltage translation portion is coupled between an input and the first node. An inverter portion has a first input connected to the first node, a second input for receiving the input clock signal, and an output for providing the output clock signal. A clamping portion is connected to the first node to minimize the bias voltage potential.
