Abstract
1416376 Transistor logic circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 April 1973 [20 April 1972] 18435/73 Heading H3T [Also in Divisions H2] A transistor logic circuit comprises a first NAND gate having inputs G1, G2 and a second NAND gate having inputs G3, G4. A D.C. source is connected across terminals P, Q and when the potential at the positive terminal of the source is applied to the input G1, a transistor 109 is switched off whilst a transistor 111 is switched on. The output terminal Q1 is therefore at the negative potential of the source and is applied to the input G3 of the second gate. Similarly when the negative potential of the source is applied to the input terminal G1 the states of the transistors 109, 111 are reversed and the potential at the terminal Q1 equals the positive potential of the source.
