DS275 Line Powered RS232 Transceiver IC (DIP 8, Low Power)

The DS275 is a low power RS232 transceiver IC originally developed by Dallas Semiconductor. It provides serial communication between RS232 interfaces and CMOS or TTL logic circuits. Its power saving transmitter design uses the incoming RS232 receive line to help generate negative transmit voltage, reducing static power consumption in battery powered systems. It is suitable for compact serial communication interfaces where low power consumption is important.
