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.
