HV528 16-Channel Serial to Parallel Converter with High Voltage Backplane Driver and Push-Pull Outputs Features General Description HVCMOS technology The HV528 is a 200V, 16-channel serial to parallel converter. The high voltage outputs and the backplane driver are Output voltage up to +200V designed to source and sink 1.0mA. Shift register speed 500kHz V = 1.7V DD 16 high voltage outputs The high voltage outputs are controlled by a 16-bit serial shift High voltage backplane driver register, followed by a 16-bit latch. Data is shifted through CMOS input levels the shift registers during the low to high clock transition. A data output buffer is provided for cascading multiple devices. Data is transferred to the 16-bit latch when a logic level low is Applications applied to the LE input. Data is stored in the latch when LE is high. Output states are controlled by the data in the latch and Multiple segment EL display by the POL pin.

External ground noise reduction circuit will be provided by design upon characterization. Power-up sequence should be the following*: 1. Apply ground 2. Apply V DD 3. Set all inputs (D , CLK, LE , POL) to a known state IN 4. Apply V BIAS 5. Apply V PP Power-down sequence should be the reverse of the above * This power up sequence requires an external high voltage diode between V and V . Without the diode, power up V to a V level rst to bias DD PP PP DD the silicon substrate. After all other signals are powered, nish raising the V to its nal level.
