HV2201PJ-G-M904

Analog Switches - Special Purpose Overview

The HV2201PJ-G-M904 is an enhanced, low charge injection, 8-channel high voltage analog switch IC manufactured by Supertex Inc. (Microchip Technology). It utilizes HVCMOS technology to combine high voltage bilateral DMOS switches with low power CMOS logic. The device accepts 3.3V or 5.0V CMOS input logic and features a cascadable serial data register with latches. It supports flexible operating supply voltages, including VPP/VNN combinations of +40V/-160V, +100V/-100V, and +160V/-40V. Key electrical parameters include a 20MHz data shift clock frequency at 5.0V VDD, DC to 50MHz analog signal frequency capability, -60dB typical off-isolation at 5.0MHz, and very low quiescent power dissipation of -10µA.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix 'G' confirms RoHS compliance as indicated in the datasheet. Confirm the package type matches the 28-Lead PLCC designation associated with the PJ suffix. Ensure the component source is traced to Supertex Inc. or its successor Microchip Technology to guarantee authenticity and adherence to original manufacturing specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high voltage analog switching driven by standard 3.3V or 5.0V digital logic. Consider the 28-lead PLCC package if board space constraints align with its dimensions. Evaluate the need for low charge injection and high off-isolation characteristics for sensitive analog signal paths. Verify that the required VPP and VNN supply rails fall within the specified operational ranges for the target application.

Analog Switches - Special Purpose Part Context

The HV2201PJ-G-M904 belongs to the HV2201 family of high voltage analog switches. It serves as an enhanced version of the earlier HV20220 model. The device is part of Supertex Inc.'s portfolio, which was acquired by Microchip Technology. This series is designed specifically for applications demanding reliable high voltage switching with minimal signal distortion and low power consumption.

Analog Switches - Special Purpose Replacement Considerations

The datasheet identifies the HV2201 as an enhanced version of the HV20220. Designers may consider the HV20220 as a predecessor part, though functional equivalence should be verified against specific application requirements. No other direct substitute part numbers are explicitly listed in the provided documentation.
