Introduction

PI5V330SQEX is a special purpose analog switch which belongs to the interface – analog switches – special purpose category. It is a multiplexer/demultiplexer (MUX/DEMUX) switch device for digital/analog control. It is a three-to-one (1:3) or one-to-three (3:1) multiplexer/demultiplexer switch, depending on the operating mode. It offers multiple switching systems, making it ideal for reducing wiring, increasing system reliability and reducing the difficulty of re-wiring.

Application fields

PI5V330SQEX is qualified for use in harsh environments, such as in industrial, automotive and communication applications. It can be used in applications such as:

• Automotive audio and infotainment systems
• Automotive control/driver information systems
• Industrial environments, such as mining, oil and gas
• Communication systems, such as radio and cellular
• Medical systems, such as patient monitoring

It is especially suitable for applications where multiple signals need to be transferred and switched simultaneously, such as in communication systems.

Features

The PI5V330SQEX has some key features that make it suitable for harsh environments:

• Operating temperature range of -40℃ to 125℃
• Ultra-low on-state resistance (< 20 mOhm) due to active-low switch control
• Minimum capacitance (~ 5 pF)
• Durable and EMI-resistant contact surfaces
• Long lifetime of two million cycles

This switch is capable of operating with a varying voltage and current ranges, making it suitable for different system requirements.

Working Principle

The PI5V330SQEX is a three-to-one (1:3) or one-to-three (3:1) multiplexer/demultiplexer switch, depending on the operating mode. The switch is controlled by an active-low input signal. When in multiplexer mode, the switch has three input channels and one output channel. When in demultiplexer mode, the switch has one input channel and three output channels. The switch is composed of three N-channel metal-oxide semiconductor field-effect transistors (MOSFET). The gates of these transistors are used to control the switching. When the control input is low, the gates of the transistors are grounded, allowing current to flow through the switch. When the control input is high, the gates of the transistors are high, making the switch off and isolating the output channel from the input channels.

Conclusion

The PI5V330SQEX is a special purpose analog switch belonging to the interface – analog switches – special purpose category. It is a reliable, cost-effective switch device ideal for reducing wiring complexity and increasing system reliability. It is suitable for harsh industrial, automotive and communication applications, as it offers a long lifetime of two million cycles, EMI-resistant contact surfaces, minimal capacitance and low on-state resistance. The switch is a three-to-one (1:3) or one-to-three (3:1) Multiplexer/Demultiplexer depending on the operating mode and is composed of three N-channel MOSFETs.
