The HV7022C is a low-voltage serial to high-voltage parallel?converter with push-pull outputs. It is especially suited for use?as a symmetric row driver in AC thin-film electroluminescent?(ACTFEL) displays. The HV7022C offers 34 output lines, a?direction (DIR) pin to give CW or CCW shift register loading,?output enable (OE), and polarity (POL) control. After data is?entered (on the falling edge of CLK), a logic high will cause?the output to swing to VPP if POL is high, or to GND if POL?is low.
