HV528

HV528 16-Channel Serial to Parallel Converter with High Voltage Backplane Driver and Push-Pull Outputs Features ► HVCMOS® technology ► Output voltage up to +200V ► Shift register speed 500kHz @ VDD = 1.7V ► 16 high voltage outputs ► High voltage backplane driver ► CMOS input levels Applications ► Multiple segment EL display ► Piezoelectric transducer driver ► Braille driver General Description The HV528 is a 200V, 16-channel serial to parallel converter. The high voltage outputs and the backplane driver are designed to source and sink ±1.0mA. The high voltage outputs are controlled by a 16-bit serial shift register, followed by a 16-bit latch. Data is shifted through 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 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 by the POL pin.
