Maxim Integrated DS275S Line-Powered RS-232 Transceiver Module

The Maxim Integrated DS275S is a highly efficient line-powered RS-232 transceiver module designed for applications where minimal power consumption and space are critical. This innovative product offers a unique solution for RS-232 communication, particularly in situations where traditional power supplies are inconvenient or unavailable. It draws power directly from the data lines, eliminating the need for an external power source and simplifying the overall design for engineers and developers.

The DS275S is an ideal choice for portable or compact devices such as handheld terminals, PDAs, and battery-powered equipment. Its low-power operation and small footprint make it an excellent option for applications where efficiency and size are paramount. The module integrates charge-pump circuitry that generates RS-232 voltage levels from a single 3.0V to 5.5V supply provided by the data lines, which is a significant advantage in power-sensitive designs.

This transceiver supports data rates up to 250kbps, providing a balance between speed and power usage. It is fully compliant with the EIA/TIA-232-E standards and is capable of withstanding ±15kV ESD hits, thereby offering robust protection for your communication interfaces against electrostatic discharges.

The DS275S features a low-power shutdown mode that further reduces power consumption when the device is not in use, which is particularly useful in battery-operated devices where energy conservation is essential. The module's small SOT-23 package makes it easy to integrate into existing designs without requiring significant board space, allowing for more compact and streamlined product designs.

Overall, the Maxim Integrated DS275S is a versatile, reliable, and energy-efficient solution for RS-232 data communication. Its ability to operate without an external power supply, coupled with its ESD protection and compliance with industry standards, makes it a top choice for designers looking to enhance their products with robust and efficient serial communication capabilities.
