Abstract
A decoder formed of multiple circuit blocks each including bipolar transistors Q1 and Q2 having their collectors connected to resistors R1 and R2, respectively, a bipolar transistor Q3 having its collector supplied with a power voltage, and a current source I1 connected commonly to the emitters of Q1-Q3. This circuit configuration permits the decoder and BiCMOS memories using it to operate with a low supply voltage.
