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 V
PP
if POL is high, or to GND if POL is low.

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