HV513WG SOP-24 is a low-voltage-to-high-voltage serial-to-parallel converter with eight high-voltage push-pull outputs. This device is designed to drive small capacitive loads such as piezoelectric transducers. It can also be used in any application requiring multiple high-voltage outputs with medium-current source-and-sink capabilities. The device consists of an 8-bit Shift register, eight 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.
The operation of the Shift register is not affected by the latch enable (LE), blanking (BL), polarity (POL) and Hi-Z control inputs. The 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 Hi-Z pin is provided to set all the outputs in a High-Z state.
