General Description

- RS-232 Receiver Output - Transmit driver +V - RS-232 Driver Input - System Ground (0V) - RS-232 Driver Output - No Connection - RS-232 Receive Input -System Logic Supply (+5V) DESCRIPTION The DS275 Line-Powered RS-232 Transceiver Chip is a CMOS device that provides a low-cost, very low-power interface to RS-232 serial ports.

The receiver input translates RS-232 signal levels to common CMOS/TTL levels.

The transmitter employs a unique circuit which steals current from the receive RS232 signal when that signal is in a negative state (marking).
