Description
AI
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.
