General Description
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 piezoelectric transducers. It
can also be used in any application requiring multiple high voltage
outputs, medium current sourcing and sinking capabilities.
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 SEL is low. The data is held in the
output latches whenever LE is low.
The high voltage output state is primarily dependent on the value
in the polarity latch. If 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.
All outputs with have a break-before-make circuitry to reduce
cross-over current during output state changes.
Note:
1. LE, SEL, and BL have internal 20kΩ pull-up resistors.
