General Description
The HV4622 is a low-voltage serial to high-voltage parallel
converter with P-Channel open drain outputs. This device has
been designed for use a driver for AC-electroluminescent
displays. It 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.
This device consists 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 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 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
HV4622 can be paired with the HV5622.
