HV528K6-G

Shift Registers Overview

The HV528K6-G is a 16-channel serial to parallel converter utilizing HVCMOS technology. It features high voltage outputs capable of sourcing and sinking ±1.0mA, controlled by a 16-bit shift register and latch. The device operates with a logic supply (VDD) from 1.7V to 5.5V and a high voltage supply (VPP) up to 200V. The shift register speed reaches 500kHz at VDD = 1.7V. It includes a backplane driver and push-pull outputs in a 32-lead QFN package.
