HV214PJ-G

Analog Switches - Special Purpose Overview

The HV214PJ-G is an 8-channel high voltage analog switch IC manufactured by Microchip Technology, utilizing HVCMOS technology. It operates with a logic supply (VDD) of 4.5V to 13.2V and supports flexible high voltage supplies (VPP/VNN) ranging from +40V/-210V to +210V/-40V. The device features low charge injection, small signal on-resistance up to 55Ω, and a DC to 50MHz frequency response. It includes an integrated 8-bit shift register and latch for serial control. Packaged in a 28-lead PLCC, it operates within a temperature range of 0°C to 70°C.

Analog Switches - Special Purpose Feature Summary

• Integrates an 8-bit shift register and latch for efficient serial data input and retention.
• Utilizes HVCMOS technology to combine high voltage bilateral DMOS switches with low power CMOS logic.
• Provides very low quiescent power dissipation and excellent noise immunity.

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging
• Non-destructive evaluation
• Inkjet printer heads
• Optical MEMS modules

Analog Switches - Special Purpose Procurement Notes

Verify the component origin as Supertex Inc., which was acquired by Microchip Technology. Confirm that the ordering suffix -G indicates a lead-free and RoHS compliant package. Ensure the specific package type matches the required footprint, as this part number corresponds to the 28-lead PLCC option.

Analog Switches - Special Purpose Selection Notes

Select the HV214PJ-G when high voltage switching capabilities are required alongside low voltage digital control signals. This component is suitable for designs needing flexible dual supply configurations and low parasitic capacitances. Verify that the operating temperature range and package dimensions align with the system constraints.

Analog Switches - Special Purpose Part Context

The HV214 series consists of low charge injection, 8-channel high voltage analog switches. The PJ-G suffix specifically denotes the 28-lead Plastic Leadless Chip Carrier (PLCC) package variant. Other variants include the FG-G option available in a 48-lead LQFP package.

Analog Switches - Special Purpose Replacement Considerations

The HV214FG-G serves as a pin-compatible alternative within the same family, offering identical electrical characteristics but housed in a 48-lead LQFP package instead of the 28-lead PLCC.

Analog Switches - Special Purpose FAQ

What is the maximum peak analog signal current per channel?

The absolute maximum rating for peak analog signal current per channel is 2.5A.

How does the latch enable bar affect data clocking?

To reduce clock feedthrough noise, the latch enable bar should be left high until all bits are clocked into the shift register.

What is the typical output off isolation at 5.0MHz?

The typical output off isolation is -60dB at 5.0MHz with a 50Ω load.
