HV513

8-Channel Serial to Parallel Converter with High Voltage

Push-Pull Outputs, POL, Hi-Z, and Short Circuit Detect

Features

General Description

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 piezoelec-

tric transducers. It can also be used in any application requiring

multiple high voltage outputs, with medium current source and

sink capabilities.

❑

HVCMOS‚ technology

Operating output voltage of 250V

Low power level shifting from 5V to 250V

Shift register speed 8MHz @ V_DD= 5V

8 latch data outputs

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. A data 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 polarity and blanking

CMOS compatible inputs

Output short circuit detect

Output high-Z control

Applications

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.

❏

Piezoelectric transducer driver

Weaving applications

Braille

Printers

All outputs will have a break-before-make circuitry to reduce

cross-over current during output state changes.

MEMs

Displays

The POL, BL, LE, and HI-Z inputs have an internal pull up

resistor.

Notes:

1. Below minimum V_PPthe output may not switch.

2. Power-up sequence should be the following:

1. Connect ground.

2. ApplyV_DD

3. Set all inputs (Data, CLK, Enable, etc.) to a known state.

4. ApplyV_PP.

Power-down sequence should be the reverse of the above.
