HV2761FG-G

Analog Switches - Special Purpose Overview

The HV2761FG-G is a 24-channel high voltage analog switch IC manufactured by Microchip Technology (originally Supertex). It operates with flexible dual supplies, typically VPP/VNN ranging from +40V/-160V to +160V/-40V. The device features integrated bleed resistors and low charge injection. Logic control uses 3.3V or 5.0V CMOS levels via a serial shift register. Key electrical parameters include an ON-resistance of approximately 26 Ohms at +40V/-160V, quiescent current of 10µA, and a maximum clock frequency of 20MHz at 5.0V. It supports DC to 50MHz analog signal frequencies and operates within a temperature range of 0°C to +70°C in a 48-lead LQFP package.
