Notes:
1. All voltages are referenced to GND.
2. Duty cycle is limited by the total power dissipated in the package.
3. For operation above 25°C ambient derate linearly to maximum operating temperature at 20mW/ for plasitc and at 15mW/ for ceramic.

The HV5122 and HV52 are low voltage serial to high voltage parallel converters with 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 sinking capabilities such as driving inkjet and electrostatic print heads, plasma panels, vacuum fluorescent, or large matrix LCD displays.

These devices HV5122 consist 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 HV5122 shifts in the counterclockwise direction when viewed from the top of the package and the HV52 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. Operation of the shift register is not affected by the OE (Output Enable) or the STR (Strobe) inputs.

The HV5122 and HV52 have 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.
