General Description

RXOUT VDRV+ TXIN GND TXOUT VDRVRXIN VCC RS-232 Receiver Output Transmit Driver Positive Supply RS-232 Driver Input System Ground (0V) RS-232 Driver Output Transmit Driver Negative Supply RS-232 Receiver Input System Logic Supply (3-5V) ORDERING INFORMATION DS276 DS276S 8-Pin DIP 8-Pin SOIC DESCRIPTION The DS276 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 can be used with independently supplied positive and negative supplies, but in most cases will be used with the positive supply, sharing the logic supply and the negative supply stolen from the receive RS-232 signal when that signal is in a negative state (marking).

Key Features

Low-power serial transmitter/receiver for battery-backed systems Transmitter steals power from receive signal line to save power Single 3V or 5V operation Full duplex operation up to 20k bps Ultra-low static current Compatible with RS-232-E signals PIN.
