The DS275 Line-Powered RS-232 Transceiver Chip derives power from the data line providing an extremely low-cost and low-power RS-232 serial port interface. The receiver input translates RS-232 signal levels to common CMOS/TTL levels. The transmitter circuit steals current from the receive RS-232 signal when that signal is in a negative state (marking). Since most serial communication ports remain in a negative state statically, using the receive signal for negative power greatly reduces the DS275's static power consumption.
The DS275's power-saving interface is ideal for connecting battery-powered systems such as laptop computers, remote sensors, and portable instrumentation.
