HV5522
32-Channel Serial-to-Parallel Converter with Open Drain Outputs
Features General Description The HV5522 is a low-voltage to high-voltage
serial-to-parallel converter with open drain outputs.
This device is 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. 100 mA Minimum Sink Current
8 MHz Shift Register Speed
Polarity and Blanking Inputs
CMOS-compatible Inputs
Forward and Reverse Shifting Options
Diode to VPP allows Efficient Power Recovery Applications Inkjet and Electrostatic Print Heads AC-electroluminescent Displays Microelectromechanical Systems Applications 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
HV5522 shifts the data counter clockwise 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 …
