General Description
The Supertex HV508 is a 45V liquid crystal shutter driver in an SO-
8 surface mount package. It consist of two outputs that provide
square waves of opposite phase. The liquid crystal shutter is
connected between the two outputs. Its equivalent load can be
approximated as a resistor in parallel with a capacitor. Minimum
resistance is 1.0MΩ and maximum capacitance is 0.1µF.
The HV508 has three input supply voltages, HV
