| ST202 5V POWERED MULTI-CHANNEL RS-232 DRIVERS AND RECEIVERS s s s s s s s s s SUPPLY VOLTAGE RANGE: 4.5 TO 5.5V SUPPLY CURRENT NO LOAD (TYP): 1.5mA TRASMITTER OUTPUT VOLTAGE SWING (TYP): 9V TRANSITION SLEW RATE (TYP.): 12V/s RECEIVER PROPAGATION DELAY (TYP.): 0.1s COMPATIBLE WITH MAX202 RECEIVER INPUT VOLTAGE RANGE: 30V DATA RATE (TYP.): 400Kbp/s OPERATING TEMPERATURE RANGE: -40 TO 85 C, 0 TO 70C DIP SOP DESCRIPTION The ST202 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 ST202 uses a single 5V power supply and only four external capacitors (0.1F). Typical application are in: Portable Computers, Low Power Modems, Interfaces Translation, Battery Powered RS-232 Networks.
