HV51

The HV51 and HV52 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 electroluminescent 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 and control logic to perform the output enable and All-ON functions. Data is shifted through the shift register on the logic high to low transition of the clock. The HV51 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 HV51 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.
