ABSTRACT:
A driving circuit with low power consumption and high operational speed, and including transistors Q.sub.1, Q.sub.2, Q.sub.3, Q.sub.4, P.sub.1 and P.sub.2, resistors R.sub.1 and R.sub.2, and diodes D.sub.1 and D.sub.2 which form a high-level feeding circuit for setting the output terminal level at the high level; and a constant-current source I.sub.BS, current mirror circuit MR.sub.12, transistors Q.sub.11, Q.sub.13 and Q.sub.14, resistor R.sub.11, and Schottky diode DS.sub.11 which form a low-level feeding circuit for setting the output terminal level at the low level. When the output terminal (T.sub.out) level is changed to the high level or low level, a large current flows into the base of transistor Q.sub.3 or Q.sub.13, and a rapid change takes place for the output terminal level. When the output terminal level reaches the prescribed voltage, the current flowing into the base of transistor Q.sub.3 or Q.sub.13 disappears. Consequently, the power consumption is reduced in the steady state when the output terminal level is steady.
