MAX202CUE+

The MAX202CUE+ is an integrated multi-channel RS-232 driver/receiver IC from Maxim Integrated that provides a simple way to enable RS-232 communication in applications where power and/or space are limited. It provides up to two channels of industry-standard full-duplex RS-232 communication. Each channel consists of a low-power driver and receiver, while the MAX202CUE+ also provides a range of other features, including undervoltage lockout, transient protection, and precise level-shifting. With a wide operating voltage range of 2.7V to 5.5V, the MAX202CUE+ is an ideal choice for applications such as embedded systems, portable and battery-operated equipment, and instrumentation.

Application Field

The MAX202CUE+ is designed for a broad range of applications that require the ability to send and receive digital data using industry-standard RS-232 communication. These applications include, but are not limited to, embedded systems, industrial automation and control, instrumentation and metering, point-of-sale systems, smart meters, and portable devices. The MAX202CUE+ is available in commercial, industrial and automotive temperature ranges to guarantee reliable performance.

Working Principle

The MAX202CUE+ is designed to provide up to two channels of reliable full-duplex RS-232 communication. Each channel consists of a low-power driver and receiver, enabling communication in a wide variety of conditions. The driver is capable of driving signals up to 30kbps, while the receivers sense signals down to 0V, enabling reliable operation in applications with low signal levels. The device also includes voltage-level shifting, allowing operation between any two signal voltage ranges of 2V to 5V and 0 to 5V. The MAX202CUE+ also includes transient-protection circuitry to limit signal spikes, along with undervoltage-lockout circuitry to ensure reliable operation in applications with power supply issues.
