The device is a low-on-state resistance CMOS analog switch, featuring a built-in multiplexer for independent control of two output channels, providing a maximum channel switching capability of 4A. The MAX4740ETE+ is a versatile switch that can be used for both single-pole and dual-pole configurations.

The MAX4740ETE+ switch is a low-power CMOS analog switch featuring an integrated multiplexer. This integrated multiplexer allows independent control of two output channels within the same package and provides a maximum channel switch capacity of 4A. The versatile switch can be used in both single and dual pole configurations to match the application requirements. The low on-state resistance of the switch ensures a low-noise operation, while the built-in glitch-free feature prevents noise spikes during switching operation.

The MAX4740ETE+ is suitable for a wide range of applications, including automotive, communication, industrial, and consumer. It is designed for use in applications such as power supplies, audio/video signal routing, and general switching applications. The MAX4740ETE+ also offers a controlled slew rate for improved audio quality, wide voltage and current ratings, and a high-speed switching capability. It’s TTL/CMOS compatible logic levels ensure a wide range of compatibility with logic devices.

The versatile analog switch of the MAX4740ETE+ offers protection from electrostatic discharge, so it can be used in applications requiring high ESD protection. The ETS0 junction temperature of the device can reach up to +125°C, making it suitable for applications requiring high temperatures. The switch is provided in a 16-pin TSSOP package, and features overcurrent protection, soft-start switching, and current limit protections.

In operation, the MAX4740ETE+ is an analog switch allowing independent control of both output channels. The switch operates in an open-drain configuration, allowing both input and power connections to be connected simultaneously. The device can be powered by a single supply or separate supplies for each input and output channels. A logic high signal is applied to the logic input pins to turn the switch on and a logic low to turn it off. Outputs are disconnected from the input signal when the switch is in the off-state, preventing signal interference during switching. The integrated low-on-state resistance provides a signal path with very low signal attenuation for minimal signal distortion.

The MAX4740ETE+ is an ideal solution for a wide range of applications that require ultra-low on-state resistance, high channel switching capability, ESD protection, and wide operating temperature range. The device is a versatile switch that is suitable for both single and dual pole configurations, and provides high voltage and current ratings for improved performance. This device, provided in a 16-pin TSSOP package, offers overcurrent protection, power-up control with soft-start switching, and current-limit protection.
