General Description
The HV510 is a low voltage serial to high voltage parallel con-
verter with 12 high voltage push-pull outputs. This device has
been designed to drive small capacitive loads such as piezo
electric transducers. It can also be used in any application
requiring multiple high voltage outputs, low current sourcing and
sinking capabilities.
The device consists of a 12-bit shift register, 12 latches, and
control logic to perform the polarity select and blanking of the
outputs. A DIR pin controls the direction of data shift through the
device. With DIR grounded, DIOA is Data In and DIOB is Data Out;
data is shifted from HVOUT12 to HVOUT1. When DIR is at logic high,
DIOB is Data In and DIOA is Data Out: data is then shifted from
HVOUT1 to HVOUT12. Data is shifted through the shift register on
the low to high transition of the clock. Data output buffers are
provided for cascading devices. Operation of the shift register is
not affected by the LE, BL, or the POL inputs. Transfer of data from
the shift register to the latch occurs when the LE is high. The data
in the latch is stored during LE transition from high to low.

Notes:
1. All voltages are referenced to GND.
2. Connection to all power and ground pads is required. Duty cycle is limited by
the total power dissipated in the package.
3. For operation above 25°C ambient derate linearly to 85°C at 12mW/°C.
