General Description
The Supertex HV508 is a 45V liquid crystal shutter driver in
an 8-Lead SOIC surface mount package. It consists 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, HVIN, LVIN, and
VDD. The output’s amplitude will be either LVIN or HVIN. A logic
high on the HVEN input will set the output to operate from the
HVIN supply. A logic low on the HVEN input will set the output
to operate from the LVIN supply. The output frequency is set
by the logic input frequency applied on the POL input.

Absolute Maximum Ratings are those values beyond which damage to the device may
occur. Functional operation under these conditions is not implied. Continuous operation
of the device at the absolute rating level may affect device reliability. All voltages are
referenced to device ground.
Notes:
1. For operation above 25OC ambient, derate linearly at 6.0mW/OC.
