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.

Absolute Maximum Ratings are those values beyond which damage to the
device may occur. Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level may affect
device reliability. All voltages are referenced to device ground.

Power-up sequence should be the following*:
1. Apply ground
2. Apply VDD
3. Set all inputs (DIN, CLK, LE , POL) to a known state
4. Apply VBIAS
5. Apply VPP
Power-down sequence should be the reverse of the above
