The HV55 and HV56 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 consist 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 HV55 shifts in the counterclockwise direction when viewed from the top of the package, and the HV56 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 LE (latch enable), BL (blanking), or the POL (polarity) inputs. Transfer of data from the shift register to the latch occurs when the LE (latch enable) input is high. The data in the latch is stored when LE is low.
Supply voltage, VDD1 Output voltage, HV5530/HV5630 HV5522/HV5622 Logic input Ground to +230V
Operating temperature range Storage temperature range Lead temperature 1.6mm (1/16 inch) from case for 10 seconds
Notes: 1. All voltages are referenced to VSS. 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 20°C for plastic and at 15mW/°C for ceramic.
