HV508

Supertex inc. HV508 High Voltage, Liquid Crystal Shutter Driver Features ►►HVCMOS® technology for high performance ►►Logic-selectable output voltage ►►100nF drive capability ►►Up to 90VP-P ►►25µs response time 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 PO...
