• Package Type: 16-TSSOP

Applications

The MAX3344EEUE+T is suitable for a wide range of applications that require reliable serial communication. It is particularly well-suited for portable devices, such as:

• Notebook, subnotebook, and palmtop computers
• Battery-powered equipment
• Handheld equipment
• Data cables
• PDAs and smartphones

Product Advantages

One of the significant advantages of the MAX3344EEUE+T is its low-power consumption, which extends the battery life of portable devices. The device also features a low-dropout transmitter output stage, enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. The charge pump requires only four small 0.1µF capacitors for operation, reducing the overall component count and board space.

The robust ESD protection ensures that the MAX3344EEUE+T can withstand the rigors of real-world handling, making it a reliable choice for applications that may be subject to electrostatic discharge. Furthermore, the wide operating temperature range makes it suitable for use in both commercial and industrial environments.
