Abstract

PURPOSE:To achieve stable operation in high speed, by differential connection of the 1st and 2nd transistors (TRs), connecting a diode between the collector of each TR and a reference potential, and applying an output of an ECL circuit to the base of the 1st and 2nd TRs. CONSTITUTION:When signals P1, P1' are applied, TRs Q2, Q5 turn on, and Q1, Q3 turn off. As a result, currents I, I1-I7 flow as shown in figure, where I3 is nearly zero. In this case, the follwing relation is obtained, I=I2+I5+I6, I1R7, I2R2=I6R6, I7R7+VBE7=Vcc-3VF, (I4+I5)R4+VBE5= I2R2 (where; VBE7, VBE5 are respectively base-to-emitter voltage of Q7, Q5). Thus, voltages at output terminals 23, 24 can be 4VF-3VF by suitably selecting the values of R1, R2, R4, allowing to turn on the Q7 and to turn off the Q6.
