General Description
The HV5622 is a low-voltage serial-to-high-voltage
parallel converter with open drain outputs. This device
has
been
designed
as
a
driver
for
AC-electroluminescent displays. It can also be used in
any application requiring multiple-output high-voltage
current-sinking capabilities such as driving inkjet and
electrostatic print heads, plasma panels, vacuum
fluorescent and large matrix LCD displays.
The device consists of a 32-bit Shift register, 32 latches
and control logic to perform the polarity select and
blanking of the outputs. Data is shifted through the Shift
register on the high-to-low transition of the clock. The
HV5622 shifts in a clockwise direction when viewed
from the top of the package. A data output buffer is
provided for cascading devices. This output reflects the
current status of the last bit of the Shift register. The
operation of the Shift register is not affected by the latch
enable (LE), blanking (BL) and polarity (POL) inputs.
Transfer of data from the Shift register to the latch
occurs when the LE input is high. The data in the latch
is stored when LE is low.
Applications
• Inkjet and Electrostatic Print Heads
• AC-electroluminescent Displays
• Microelectromechanical Systems Applications

† Notice:
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only, and functional operation of the device at those or any other conditions above those
indicated in the operational sections of this specification is not intended. Exposure to maximum rating conditions for
extended periods may affect device reliability.
Note 1:
All voltages are referenced to V
SS
.
2:
Duty cycle is limited by the total power dissipated in the package.
3:
For operations above 25°C ambient, derate linearly to the maximum operating temperature at 20 mW/°C.
