HV20220PJ-G-M904

Analog Switches - Special Purpose Overview

The HV20220PJ-G-M904 is an 8-channel high-voltage analog switch manufactured by Microchip Technology (formerly Supertex). It utilizes HVCMOS technology to combine high voltage bilateral DMOS switches with low power CMOS logic. The device operates on a dual supply configuration, supporting VPP ranges from +40V to +200V and VNN ranges from -40V to -160V. The logic supply voltage (VDD) operates between 4.5V and 13.2V. Key electrical parameters include a maximum on-resistance of 48Ω at VPP=+40V/VNN=-160V and a typical off-isolation of -60dB at 5.0MHz. The package is a 28-lead PLCC.

Analog Switches - Special Purpose Feature Summary

• Integrates an 8-bit shift register and latch for serial data control
• Features very low quiescent power dissipation
• Provides excellent noise immunity through CMOS logic circuitry
• Supports flexible high voltage supply combinations

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging
• Piezoelectric transducer drivers

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix M904 corresponds to the 28-lead PLCC package packed in reels of 500 units. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the component source is authorized to guarantee authenticity and traceability for design-in purposes.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high voltage signal switching controlled by low voltage logic signals. Consider the 28-lead PLCC package constraints and the operating temperature range of 0°C to 70°C. Evaluate the on-resistance and charge injection specifications against the specific load requirements of the application.

Analog Switches - Special Purpose Part Context

This part belongs to the HV20220 series of low charge injection, 8-channel, high-voltage analog switches. The PJ suffix indicates the 28-lead PLCC package option, while the M904 suffix specifies the reel packaging quantity. The device is functionally equivalent to other variants in the series differing only in package type or packing method.

Analog Switches - Special Purpose Replacement Considerations

The HV20220FG-G serves as a pin-compatible alternative in a 48-lead LQFP package. Verify that the target PCB footprint accommodates the different package dimensions and pin count differences if substituting between the PJ and FG variants.
