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, HV_IN, LV_IN, and
V_DD. The output’s amplitude will be either LV_IN or HV_IN. A logic
high on the HV_EN input will set the output to operate from the
HV_IN supply. A logic low on the HV_EN input will set the output
to operate from the LV_IN supply. The output frequency is set
by the logic input frequency applied on the POL input.
