HV20220TQ-G-M931

Analog Switches - Special Purpose Overview

The HV20220TQ-G-M931 is an 8-channel high-voltage analog switch IC manufactured by Microchip Technology, utilizing Supertex HVCMOS technology. It features a 48-lead LQFP package with a maximum on-resistance of 30 ohms at VPP=+40V and VNN=-160V. The device operates on a single logic supply voltage ranging from 4.5V to 13.2V. High-voltage supplies support combinations such as +40V/-160V, +100V/-100V, or +160V/-40V. Quiescent power dissipation is typically 10µA. Switching times are limited to 5µs for both turn-on and turn-off durations.

Analog Switches - Special Purpose FAQ

What is the typical quiescent current consumption?

The typical quiescent current consumption is 10µA.

How does the Latch Enable Bar (LE) pin function?

The LE pin should be left high until all bits are clocked in to reduce clock feed-through noise; it retains the shift register data in the latch upon rising edge.

What are the supported high-voltage supply combinations?

The device supports combinations such as VPP/VNN: +50V/-150V, +100V/-100V, or +160V/-40V.
