Abstract

PURPOSE:To avoid stray signal for input AC signals, by using PNP and NPN transistors with emitter common connection and taking AC logc through the coupling of diode to the collector of each transistor. CONSTITUTION:When a signal is fed from the AC input signal 1 at the logical input terminal A, it is given to the collector of the NPN transistor 9 via the diode 3 at positive cycle. On the other hand, positive voltage is fed to the base of the transistor 9 via the resistor 7 from the AC power supply 13, and the transistor 9 is turned on. Next, at negative cycle, it is given to the collector of the PNP transistor 10 via the diode 5. On the other hand, negative voltage is fed to the base of the transistor 10 via the resistor 11, and the transistor 10 is turned on. Further, output voltage is caused at the emitter common junction of the transistor 9 and 10 being the output terminal Y.
