Title:
半導体装置
Document Type and Number:
Japanese Patent JP7114268
Kind Code:
B2
Abstract:
Provided is a level shifter which can retain an operation margin and enhance an exceeded-breakdown-voltage preventing effect. The level shifter in an embodiment includes an exceeded-breakdown-voltage prevention circuit between a pair of first-conductivity-type cross-coupled transistors and a pair of second-conductivity-type input transistors. The exceeded-breakdown-voltage prevention circuit includes first-conductivity-type first transistors and second-conductivity-type second transistors which are coupled in series to each other, and first-conductivity-type third transistors coupled in series to the first and second transistors on a higher-potential side.
