HV5624K7-G

Specialty Logic Overview

The HV5624K7-G is a low-voltage serial-to-high-voltage parallel converter manufactured by Microchip Technology. It features open-drain outputs and operates within a logic supply voltage range of 4.5 V to 5.5 V, supporting high-voltage outputs up to +220 V. The device includes a 32-bit shift register, 32 latches, and control logic for polarity selection and blanking. It supports clock frequencies up to 16 MHz with a propagation delay of 35 ns. The component is housed in a 44-lead WQFN package and functions reliably across an operating ambient temperature range of -40°C to +85°C.

Specialty Logic Feature Summary

• Provides 32-channel serial-to-parallel conversion with open-drain outputs capable of sinking a minimum of 100 mA.
• Integrates a 32-bit shift register and latch system with dedicated inputs for data shifting, polarity inversion, and output blanking.
• Features CMOS-compatible logic inputs and a data output pin designed for cascading multiple devices.

Specialty Logic Applications

• Driving AC-electroluminescent displays
• Actuating inkjet and electrostatic print heads
