摘要:
To a level shift basic circuit having a CMOS configuration and composed of four transistors M1 through M4, a control circuit for preventing feed-through current through the transistors is added. Transitions of complementary data inputs Vin1 and Vin2 are made in a period in which n-MOS transistors M7 and M8 for control are turned OFF by changing a control input VS1 to an L level (switch-off period). In this switch-off period, each source of the n-MOS transistors M1 and M2 is disconnected from VSS. In addition, in the switch-off period, a control input VS2 is changed to an L level, thereby turning ON p-MOS transistors M5 and M6 for control. In a period in which the control p-MOS transistors M5 and M6 are ON, data outputs Vout1 and Vout2 are both precharged to VDD (precharge period).
