<p>A select buffer circuit includes a first inverter circuit (14), a second inverter circuit (16) connected to the first, and a circuit for charging and discharging the base of an inverter transistor in the second inverter circuit from a node in the first inverter circuit. The charging and discharging circuit includes a Schottky diode (134) connected to the inverter transistor, a Schottky transistor (132) connected in series with the diode, and a resistor (130) for coupling the base of the Schottky transistor to the node in the first inverter circuit. A bipolar multiplexer including the select buffer circuit offers the advantage of an improved output waveform.</p> |
