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). By using  
an external reservoir capacitor and Schottky diode (see Figure 4) this negative supply can be maintained  
even during full-duplex operation. Since most serial communication ports remain in a negative state  
statically, using the receive signal for negative power greatly reduces the DS276’s static power  
consumption. This feature is especially important for battery-powered systems such as laptop computers,  
remote sensors, and portable medical instruments. During an actual communication session, the DS276’s  
transmitter will use system power (3-12 volts) for positive transitions while still employing the receive  
signal for negative transitions.
