General Description

TThe HV4522 and HV4622 are low-voltage serial to high-

voltage parallel converters with P-Channel open drain outputs.

These devices have been designed for use as drivers for AC-

electroluminescent displays. They can also be used in any

application requiring multiple output high-voltage current source

capabilities, such as driving inkjet and electrostatic print heads,

plasma panels, or vacuum ﬂ uorescent displays.

These devices consist of a 32-bit shift register, 32 data latches,

and control logic to perform polarity and blanking functions.

Data is shifted through the shift register on the logic high-to-

low transition of the clock. The HV4522 shifts in the counter

clockwise direction, while the HV4622 shifts in the clockwise

direction (when viewed from the top of the package). A data

output buffer is provided for cascading devices. This output

reﬂ ects the current status of the last bit of the shift register. The

data in the shift register is latched when the latch enable pin is

brought to logic high, and then returned to ground. If the latch

enable pin is held high, the latch becomes transparent and the

shift register data is directly reﬂ ected in the outputs.

For applications requiring active pull down as well as pull up, the

HV4522 and HV4622 can be paired with the HV55 and HV56

devices, respectively.
