96-Channel Serial to Parallel Converter with Push-Pull Outputs

Microchip Technology 

HV582

3.0 FUNCTIONAL DESCRIPTION

The HV582 is a unipolar, 96-channel low-voltage serial

to high-voltage parallel converter. The device consists

of six parallel 16-bit shift registers, a 96-bit latch and

96 high-voltage outputs.

The six independent shift registers allow data to be

updated into the 96-bit latch at six times the speed of a

single register (30 MHz), providing a fast update rate

for the 96 output channels. The 96-bit latch holds the

data for the high-voltage output channels; whether it is

a High-level or Low-level state. The flow of the input

data can switch direction from clockwise (D1-6A to D1-

6B) to counter-clockwise (D1-6B to D1-6A) by con-

trolling the DIR pin. A reset pin (RST) is provided to

clear the contents of the latches. All channels can be

set at the same time to a high-impedance state

(High Z), Low-level state, High-level state, or to alter

their polarity through the OE, OL, OH and POL pins,

respectively.

The high-output voltages (HVOUTn) can operate from

10V to 80V with a maximum current source and sink

capability of 75 mA.

3.1 Application Information

HV582 is designed for applications requiring multiple

high-voltage outputs with current sinking and sourcing

capabilities in the range of ±75 mA. Typical

applications where the HV582 is utilized are in plasma

displays, Inkjet printer drivers and 3D printer drivers.
