HV219FG-G

Analog Switches - Special Purpose Overview

The HV219FG-G is an 8-channel, 200V analog switch IC manufactured using Supertex HVCMOS technology. It features a typical on-resistance of 11Ω and low charge injection. The device operates with flexible dual high-voltage supplies, supporting configurations such as +40V/-160V, +100V/-100V, or +160V/-40V. Logic control is managed via an 8-bit serial shift register with latches, requiring a VDD supply between 4.5V and 13.2V. It is housed in a 48-lead LQFP package.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type. The standard FG variant typically utilizes tray packing, while M931 variants utilize reel packing. Confirm RoHS compliance status and lead-free designation directly from the manufacturer's current datasheet before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high voltage switching capabilities up to 200V with low insertion loss. The 11Ω on-resistance makes it suitable for applications demanding reduced signal attenuation. Ensure the design accommodates the required dual high-voltage supply rails and serial logic interface timing constraints specified in the electrical characteristics.

Analog Switches - Special Purpose Part Context

The HV219 is part of the Supertex high-voltage analog switch family. It serves as a lower switch resistance alternative to the HV20220 device, offering 11Ω versus 22Ω on-resistance to reduce insertion loss. It shares the same pin configuration as the HV20220PJ and HV20220FG, facilitating potential design upgrades within existing architectures.

Analog Switches - Special Purpose Replacement Considerations

The HV219 shares pin compatibility with the HV20220 series. When substituting, verify that the target application can accommodate the specific on-resistance and voltage rating differences. Ensure the replacement part meets the required high-voltage isolation and serial control interface requirements.
