Abstract
A voltage leveling circuit ( ) for use as a bi-directional device to translate logic states represented by a first voltage level to logic states represented by a second voltage level. Voltage leveling circuit uses pass transistor ( ) and pass transistor ( ) connected in a serial fashion to control current flow between the first data terminal (D ) and the second data terminal (D ). Once current flow is controlled, pull up resistors ( ) and ( ) are used to perform the voltage level shifting. Two stage ESD protection is provided for gate oxide regions of pass transistors ( ) and ( ). A control terminal(E ) is provided to allow an external disable/enable signal to control the operation of voltage leveling circuit ( ).
