Title: Semiconductor integrated circuit device
Inventor: KIKUTA SHIGERU
IPC: H03K17/22
Filed: 1988-12-05
Abstract: PURPOSE:To prevent the occurrence of latch-up even if the rise of a power voltage is steep by sharing a clamping means fixing a substrate potential to a ground potential when power is supplied and a prohibition means prohibiting the action of an internal circuit. CONSTITUTION:A pulse generation circuit 14a, a VBB clamping circuit 13, a VBB generation circuit 12, a pulse generation circuit 14b, an inverter 21, an input prohibition circuit 22, an input circuit 17 and the internal circuit 24 are generated on a semiconductor substrate 20. The parameters of respective circuits are changed in such a way that the output of the pulse generation circuit 14a goes to a high level faster than the output of the pulse generation circuit 14b. The substrate potential is clamped when power is supplied, the action of the internal circuit 24 is prohibited, and the prohibition of the action of the internal circuit 24 is released after the clamping of the substrate potential is released. Thus, latch-up at the time when power is supplied can effectively be prevented.

Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the circuit components and to adjust the luminance of a discharge tube by converting the excitation energy of a bidirectional flyback transformer into the self-excited energy satisfying the resonance condition in the flyback operation, to be fed and applied to the discharge tube. SOLUTION: A driving circuit comprises a power source part, a control circuit part, a converter circuit part of push-pull connection structure, and a set-up circuit part. The power source voltage is stabilized by a ripple current smoothening capacitor 71 connected to a DC power source 1 in parallel.
