HV582

96-Channel AC Plasma Display Data Driver

with High Voltage Push-Pull Outputs

Features

❑ Operating output voltage of 90V

❑ Data clock speed 30MHz @ V

❑ Six interleaved inputs and outputs

❑ Data directional loading control

❑ Outputs: enable, polarity, all Hi, all Lo

❑ CMOS compatible inputs

General Description

The HV582 is a low voltage to high voltage converter with 96 high

voltage push-pull outputs. This device has been designed to

operate as a data driver for AC plasma display panels.

The device is loaded at up to 30MHz using six parallel data

inputs, achieving an effective 180MHz data load rate. A direction

pin (DIR) is provided to control the data load sequence. Once

data is latched into the output latches, the outputs will be

controlled based on the latch contents, polarity (POL) pin and

output enable (OE) pin inputs. All outputs may be temporarily

forced high by asserting a ‘low’ on the OHB input. Alternatively,

all outputs may be temporarily forced low by asserting a ‘low’

on the OLB input. This versatility allows the outputs to be

individually controlled, all set high or low, or all set to a high-

Z state.

Circuitry assures a break-before-make interval when switching

the output transistors, preventing output cross-conduction,

thereby increasing power efficiency.
