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:

LE, SEL, and BL have internal 20kΩ pull-up resistors.
