HV514
8-Channel Serial to Parallel Converter
with High Voltage Push-Pull Outputs
Features
General Description
❏ HVCMOS‚ technology
The HV514 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, medium current sourcing and
sinking capabilities.
❏ Operating output voltage of 250V
❏ Low power level shifting from 5V to 250V
❏ Shift clock speed 8MHz @ VDD=5V
❏ 8 latch data outputs
The device consists of an 8-bit shift register, dual 8-bit latches,
and control logic to latch data, and control blanking of the
outputs. Data is shifted through the shift register on the rising
transition of the clock. A data output buffer is provided for
cascading devices. Operation of the shift register is not affected
by the /LE, SEL, or the /BL inputs. Transfer of data from the shift
register to the latch occurs when the /LE is high. Shift register
data is shifted to the 8-bit Data Latch when SEL is high; and shift
register data is shifted to the 8-bit Polarity Latch when SELis low.
The data is held in the output latches whenever /LE is low.
❏ Output blanking
❏ CMOS compatible inputs
❏ Programmable POL latch
Applications
❏ Piezoelectric transducer driver
❏ Weaving applications
❏ Braille
The high voltage output state is primarily dependent on the value
in the polarity latch. If the blank, /BL, is low, the output condition
is the result of a 1 being exclusively-NOR’ed with the polarity
latch value. If /BL is high, the output condition is the result of the
data latch being exclusively-NOR’ed with the polarity latch.
❏ Printers
❏ MEMs
❏ Displays
All outputs with have a break-before-make circuitry to reduce
cross-over current during output state changes.
Note: /LE, SEL, and /BL 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.
