General Description
The 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-electrolu-
minescent 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 fluorescent 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 counterclockwise
direction when viewed from the top of the package and the
HV4622 shifts in the clockwise direction. A data output buffer is
provided for cascading devices. This output reflects 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 reflected 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.
