HV513  
8-Channel Serial to Parallel Converter with High Voltage  
Push-Pull Outputs, POL, Hi-Z, and Short Circuit Detect  
Features  
General Description  
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 piezoelectric 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 5.0 to 250V  
Shift register speed 8.0MHz @ VDD = 5.0V  
8 latch data outputs  
Output polarity and blanking  
Output short circuit detect  
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.Adata  
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 high-Z control  
CMOS compatible inputs  
Applications  
Piezoelectric transducer driver  
Braille driver  
Weaving applications  
Printer drivers  
MEMs  
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.  
Displays  
All outputs will have a break-before-make circuitry to reduce cross-over  
current during output state changes.  
The POL, BL, LE, and HI-Z inputs have an internal pull up resistor.
