HV582

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 HV582 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.

HV582 circuitry assures a break-before-make interval when switching the output transistors, preventing output cross-conduction, thereby increasing power efficiency.
