Title: Output circuit with high withstand voltage
Inventor: SUMIDA HITOSHI
IPC: H03K19/0175
Filed: 2001-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a output circuit with high withstand voltage capable of decreasing power consumption and preventing malfunction of a load. SOLUTION: This output circuit with high withstand voltage consists of an output stage circuit, i.e., a CMOS circuit 1 consisting of P1 on the HIGH side and N1 on the LOW side, and a preceding stage, i.e., a CMOS circuit 2 consisting of P2 and N2. An output signal Vout is outputted from an intermediate point of the circuit 1, and a load is driven by the signal Vout. The relation between thresholds of the P1 and P2 is set to Vtp1>Vtp2. By setting Vtp1>Vtp2, since P2 is turned on earlier than P1, P1 can be prevented from being turned on in the starting process of power supply voltage. Thus, malfunctions (malfunction of a load) of a plasma display can be prevented during its maintenance period, and power consumption of the output stage circuit can be reduced also.
