General Description
The HV5622 is a low-voltage serial to high-voltage parallel
converter with open drain outputs. This device has been designed
for use 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, or
large matrix LCD displays.
This 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 the 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. Operation of
the shift register is not affected by the LE (latch enable), BL
(blanking), or the POL (polarity) inputs. Transfer of data from the
shift register to the latch occurs when the LE (latch enable) input
is high. The data in the latch is stored when LE is low.

Absolute Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation under these conditions is not implied. Continuous operation of the device
at the absolute rating level may affect device reliability. All voltages are referenced to device
ground.
Notes:
1. All voltages are referenced to V
SS
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 20mW/°C
4. 1.6mm (1/16inch) from case for 10 seconds
