Abstract
When a transistor 1 is turned off, and transistors 5 and 7 are both turned on, first and second output signals Oa and Ob both attain a first potential GND irrespective of the logic level of a second logic signal Ib and a third logic signal /Ib. When the transistor 1 is turned on and the transistors 5 and 7 are both turned off by the first logic signal Ia, a transistor 4 is turned off and a transistor 6 is turned on, whereby first and second output signals Oa and Ob attain a second potential VEE and the first potential GND, respectively. When the transistor 1 is turned on, and transistors 5 and 7 are turned off, the transistor 4 is turned on and the transistor 6 is turned off, whereby the first and second output signals Oa and Ob attain the first potential GND and the second potential VEE, respectively. Thus a composite logic circuit can be implemented with 7 transistors.
