<p>A circuit for protection against static electricity comprises a first power supply terminal (1) to which a first voltage is applied, a second power supply terminal (2) to which a second voltage lower than the first voltage is applied, a first diode (12) connected in reverse direction between the first and second power supply terminals, and a second diode (11) connected in forward direction between the first and second power supply terminals. In this configuration, either the first or the second diode is in the forward connection, whichever polarity the static charge between the first and second power supply terminals has. Therefore, any static charge flows through the forward diode and disappears promptly.</p> |
