ST232 5V POWERED MULTI-CHANNEL RS-232 DRIVERS AND RECEIVERS SUPPLY VOLTAGE RANGE: 4.5 TO 5.5V SUPPLY CURRENT NO LOAD (TYP): 5mA TRANSMITTER OUTPUT VOLTAGESWING (TYP): 7.8V CONTROLLED OUTPUT SLEW RATE RECEIVER INPUT VOLTAGE RANGE: 30V DATA RATE (TYP): 220Kbps OPERATING TEMPERATURE RANGE: -40 TO 85 oC, 0 TO 70 oC COMPATIBLE WITH MAX232 AND MAX202 DESCRIPTION The ST232 is a 2 driver, 2 receiver device following EIA/TIA-232 and V.28 communication standard. It is particularly suitable for applications where 12V is not available. The ST232 uses a single 5V power supply and only four external capacitors (0.1F). Typical applications are in: Portable Computers, Low Power Modems, Interfaces Translation, Battery Powered RS-232 System, Multi-Drop RS-232 Networks.
