Supertex has introduced HV5523 and HV5623, 32-channel high voltage serial to parallel converters from low voltage inputs for use in printer and MEMS applications. These ICs feature 32-bit shift registers capable of up to 16MHz, 32 latches, and 5V control logic to perform the polarity selection and blanking of the outputs.

HV5523 shifts data in a counter-clockwise direction, while HV5623 does so in a clockwise direction.

The ICs can be used in designs driven by an open drain output up to 220V, such as plasma panels and vacuum fluorescent or large matrix LCD displays.

Their 220V open drain outputs with 100mA minimum sink current capability lets them drive heavier piezo loads with faster slew rates.

HV5523 and HV5623 are available in a 7x7mm, 44-lead QFN package (HV5523K7-G and HV5623K7-G).
