HVCMOS‚ technology
The HV513 is a low voltage serial to high voltage parallel
converter with 8 high voltage push-pull outputs. This device has
been designed to drive small capacitve loads such as piezoelec-
tric transducers. It can also be used in any application requiring
multiple high voltage outputs, with medium current source and
sink capabilities.
Operating output voltage of 250V
Low power level shifting from 5V to 250V
Shift register speed 8MHz @ VDD=5V
8 latch data outputs
The device consists of an 8-bit shift register, 8 latches, and
control logic to perform the polarity select and blanking of the
outputs. Data is shifted through the shift register on the low to
high transition of the clock. A data output buffer is provided for
cascading devices. Operation of the shift register is not affected
by the /LE, /BL, /POL, or the /HI-Z control inputs. Transfer of data
from the shift register to the latch occurs when the /LE is high.
The data in the latch is stored when /LE is low. A high-Z, /HI-Z,
pin is provided to set all the outputs in a high-Z state.
Output polarity and blanking
CMOS compatible inputs
Output short circuit detect
Output high-Z control
Applications
❏
❏
❏
❏
❏
❏
Piezoelectric transducer driver
All outputs have short circuit protection that detects if the outputs
have reached the required output state. If output does not track
the required state, then the /SHORT pin will be low. This output
will pulse low during the output transistion period under normal
operation; see SC Timing Diagram for details.
Weaving applications
Braille
Printers
MEMs
All outputs will have a break-before-make circuitry to reduce
cross-over current during output state changes.
Displays
Note: All logic control inputs have internal 20k-ohm pull-up
resistors.

Notes:
1. Below minimum VPP the output may not switch.
2. Power-up sequence should be the following:
1. Connect ground.
2. Apply VDD
3. Set all inputs (Data, CLK, Enable, etc.) to a known state.
4. Apply VPP
.
.
Power-down sequence should be the reverse of the above.
