HV20220TQ-G

Analog Switches - Special Purpose Overview

The HV20220TQ-G is an 8-channel high-voltage analog switch IC utilizing HVCMOS technology. It features a serial interface with an 8-bit shift register and latch for control. The device supports flexible dual power supplies, typically VPP/VNN combinations such as +50V/-150V or +100V/-100V. Key electrical parameters include a logic supply voltage (VDD) range of 4.5V to 13.2V, small signal on-resistance (RONS) of 22Ω typical at 5mA, and low charge injection. It operates within an ambient temperature range of 0°C to 70°C.
