Features Processed with HVCMOS(R) technology Symmetric row drive (reduces latent imaging in ACTFEL displays) Output voltages up to 230V Low-power level shifting Source/Sink current 70mA (min.) Shift register speed 4MHz Pin-programmable shift direction 44-lead plastic & ceramic surface-mount packages Hi-Rel processing available General Description The HV7022-C 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 HV70 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 INPUT is entered (on the falling edge of CLOCK), a logic high will cause the output to swing to VPP if POL is high, or to GND if POL is low.

All voltages are referenced to GND. 2. Duty cycle is limited by the total power dissipated in the package. 3. For operation above 25C ambient derate linearly to maximum operating temperature at 25mW/C for plastic and at 15mW/C for ceramic.
