Features

• High-Voltage CMOS technology
• Symmetric row drive (reduces latent imaging in 

ACTFEL displays)

• Output voltage up to +230V
• Low power level shifting
• Source/sink current minimum 70 mA
• Shift register speed 4.0 MHz
• Pin-programmable shift direction

Description

HV7022 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 elec-
troluminescent (ACTFEL) displays. HV7022 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
V

PP

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