General Description

The HV5222 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.They 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 and control logic to

perform the Output Enable and all-on functions. Data is shifted

through the shift register on the high to low transition of the

clock. The HV5222 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 OE(Output Enable) or the STR (Strobe) inputs.

The HV5222 has been designed to be used in systems which

either switch off the high voltage supply before changing the state

of the high voltage outputs or which limit the current through each

output.
