Maxim Integrated MAX3386EEUP RS-232 Transceiver
The MAX3386EEUP from Maxim Integrated is a highly-integrated RS-232 transceiver designed to facilitate serial communication in a variety of applications. This device is part of Maxim's family of transceivers that offer robust performance for interfacing between a UART serial port and RS-232 communication standards. The MAX3386EEUP is specifically engineered to operate with a single +3.0V to +5.5V power supply, making it versatile for both portable and fixed power designs.
This transceiver features a dual charge pump circuit that generates the necessary RS-232 voltage levels (+/-10V) from a single power supply. This technology allows the MAX3386EEUP to achieve a data rate of up to 250kbps, which is suitable for many standard serial applications such as point-of-sale (POS) systems, industrial control, and telecommunications equipment.
The MAX3386EEUP comes in a compact 20-pin TSSOP package, which is ideal for space-constrained applications. The device supports two drivers and two receivers, providing full-duplex communication capability. Its receivers can handle up to +/-25V input levels, and the drivers feature short-circuit protection, ensuring reliable operation even in harsh electrical environments.
Additional features of the MAX3386EEUP include a low-dropout transmitter output stage, delivering true RS-232 performance from a 3.0V to 5.5V supply. It also offers a shutdown mode that reduces the supply current to 1µA, making it an excellent choice for power-sensitive applications. The device is fully compliant with the TIA/EIA-232-F standards and is ESD protected up to ±15kV using the Human Body Model, providing an extra layer of protection against static discharge.
The MAX3386EEUP is designed with the needs of modern electronic systems in mind, offering a reliable, compact, and energy-efficient solution for RS-232 data transmission. Whether it's for mobile, hand-held, or space-restricted applications, this transceiver provides a practical and cost-effective solution for serial communication needs.
