HV214FG-G

Analog Switches - Special Purpose Overview

The HV214FG-G is an 8-channel high voltage analog switch utilizing HVCMOS technology. It operates with a logic supply (VDD) of 4.5V to 13.2V and supports flexible dual high-voltage supplies, such as VPP/VNN combinations of +40V/-210V, +125V/-125V, or +210V/-40V. The device features on-chip shift register, latch, and clear logic for serial control. Key electrical parameters include a maximum small-signal on-resistance of 55Ω at +40V/-210V, a quiescent current of -10µA, and a DC to 50MHz frequency response. It is housed in a 48-lead LQFP package.

Analog Switches - Special Purpose Feature Summary

• Integrates low charge injection bilateral DMOS switches with CMOS logic circuitry for efficient high voltage signal control.
• Includes internal 8-bit shift register and latch architecture to minimize clock feedthrough noise during data entry.
• Provides excellent noise immunity and low parasitic capacitances suitable for precision analog applications.

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging systems
• Piezoelectric transducer drivers
• Inkjet printer heads
• Optical MEMS modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. The standard FG variant typically utilizes a tray format, while other suffixes may indicate reel packing. Confirm RoHS compliance status and lead-free designation through the latest datasheet revision before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring independent control of multiple high voltage channels via low voltage digital signals. Ensure the selected supply configuration remains within the absolute maximum ratings of 260V total span. Verify that the operating temperature range meets the application requirements of 0°C to 70°C.

Analog Switches - Special Purpose Part Context

This device belongs to the HV214 family of high voltage analog switches originally developed by Supertex Inc., which was subsequently acquired by Microchip Technology. The product line is characterized by its ability to interface standard CMOS logic levels directly with high voltage analog domains without external level shifting components.
