Title: Analog switch circuit
Inventor: TANAKA HIDEKI
IPC: H03K19/0944
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To provide an analog switch circuit that does not malfunction even receiving a voltage higher than a power supply voltage and that prevents consumption of a useless current. SOLUTION: If a signal with a higher voltage VWELL than a power supply voltage VDD is directly given to an analog switch 11, a P-channel MOS transistor (TR) being a component of the analog switch is forcibly turned on when the TR should be turned off to cause malfunction to the analog switch 11 or a forward diode is formed from an N-channel well where the P-channel MOS TR is formed toward a power supply voltage VDD terminal resulting in causing a current flowing therethrough. Then a gate voltage generating section 13 generates the same voltage as this voltage VWELL and fed to a level shifter 12 as its power supply voltage VWELL, the level shifter 12 converts the VWELL into an enable signal EN1 and by using a high level of an enable signal EN, and gives the EN1 to a substrate of a TR being a component of the analog switch 11 as its base potential.  Thus, the undesirable event as above can be prevented.
