Filed: 1985-08-20
Abstract: PURPOSE:To drive a stable large current even if a process condition is varied, by constituting a phase splitter circuit part with Darlingtone-connected transistors TRs. CONSTITUTION:A phase splitter circuit part 5 consists of Darlington-connected TRs Q5 and Q6. When a high-level signal is inputted to the input, a TR Q4 is turned off and the TR Q5 is turned on. Since TRs Q5 and Q6 are Darlington- connected, a current of a maximum of (hFE)<2> can be driven in the base of a TR Q3. The TR Q3 drives sufficiently a prescribed large current because the base current is supplied to the output TR Q3 by resistances R3-R6.
