HV2902GA-G is a kind of analog switch, belonging to special purpose, in the field of Interface. It is a low-capacitance, 8-channel, non-latching, SPDT switch designed for universal switching between two signals in wide range of applications, ranging from relay driving to industrial grade applications. It is a simple, single chip solution with low power consumption, low On-resistance, and low leakage current.

The HV2902GA-G has a basic working principle comprising a pair of input pins, which are connected to the outputs through the switch conductors. When the voltages across the input pins are equal, the switch is in a ‘close’ position. In this condition, the voltage across the common output pin is equal to the voltage at the input pins. When the voltage across the input pins is difference, the switch is in an ‘open’ position. In this condition, the voltage across the common output pin is different from the voltage at the input pins.

The switch has an ‘active high’ drive system, meaning that a logic ‘1’ applied to the drive pin will result in the switch changing its position to the ‘close’ state. A logic ‘0’ applied to the drive pin will result in the switch changing its position to the ‘open’ state. The device is rated with 4.5 VDC and 10 mA current, meaning that it can only be used with low-power circuits. The HV2902GA-G can also be used in Relay, Analog Signal Switch and Switching/Level Shifting applications.

The HV2902GA-G is available in an 8-channel SOIC-14 package, making it easy to integrate into designs with an 8-channel or fewer channels. The device also comes with an integrated complementary output for the drive pin, allowing for both single-supply and dual-supply configurations. The device provides a low On-resistance, typically less than 2.5 Ohms, on a 2.5V/5V supply voltage. It also has a low leakage current, typically less than 0.05μA, with a differential input voltage of ±10V.

In addition, the HV2902GA-G comes with a wide operating temperature range of -40°C to +125°C, ensuring reliable operation over extended periods of time. It also has full ESD protection up to 2000V, providing protection against device failure due to electrical shocks. The HV2902GA-G is the ideal choice when it comes to designs requiring low power, low resistance, and high reliability.

In summary, the HV2902GA-G is an 8-channel SPDT analog switch, rated for 4.5 VDC and 10 mA, with low leakage current and low On-resistance. It provides reliable operation over a wide temperature range, and is suitable for a variety of switching and level shifting applications. Its integrated complementary output makes it easy to integrate into designs, providing a single-supply or dual-supply solution.
