Rochester Electronics Interface - Drivers, Receivers, Transceivers DS276S

The DS276S is a low-power RS-232 transceiver designed for battery-backed systems, featuring full duplex operation up to 20 kbps. It operates on a single supply voltage of 3V or 5V and utilizes a unique power-saving mechanism by stealing power from the receive signal line during idle states, significantly reducing static current consumption. The device is compatible with RS-232-E signals and translates RS-232 levels to CMOS/TTL logic levels, making it suitable for various applications, including portable medical instruments and remote sensors. The DS276S supports both positive and negative voltage levels for transmission, with a low static current draw of approximately 50-100 nA when powered down. Its design allows for effective communication over short distances, typically less than 10 feet, while maintaining low overall power consumption.
