HV2301TQ-G

Analog Switches - Special Purpose Overview

The HV2301TQ-G is an 8-channel high-voltage analog switch IC utilizing HVCMOS technology. It features integrated bleed resistors to eliminate voltage buildup on capacitive loads like piezoelectric transducers. The device operates with flexible supply voltages, supporting VPP from +40V to VNN+200V and VNN from -40V to -160V. Logic control uses 3.3V or 5.0V CMOS levels with a quiescent current of 10µA. It includes an 8-bit shift register and latch for serial data input. The analog signal frequency range extends from DC to 50MHz, with typical off-isolation of -60dB at 5MHz.
