Ay/ ST232A VERY HIGH SPEED, ULTRA LOW POWER CONSUMPTION SV POWERED RS-232 DRIVERS AND RECEIVERS SUPPLY VOLTAGE RANGE: 4.5 TO 5.5V SUPPLY CURRENT NO LOAD (TYP): 1.5mA TRANSMITTER OUTPUT VOLTAGESWING (TYP): +9V = TRANSITION SLEWRATE (TYP.):12Viis RECEIVER PROPAGATION DELAY (TYP,):0.1us RECEIVER INPUT VOLTAGE RANGE: +30V = DATARATE(TYP): 400Kbp/s = OPERATING TEMPERATURE RANGE: -40TO85C,0 TO70C DESCRIPTION The ST232A is a 2 driver, 2 receiver device following EIA/TIA-232 and V.28 communication standard. It is particularly suitable for applications (Plastic Package) (Micro Package) a where +12V is not available. The ST232 uses a T single 5V power supply and only four external (Micro Package Large) (TSSOP Package) capacitors (0.1uF). Typical applications are in: Portable Computers, Low Power Modems, Interfaces Translation, Battery Powered RS-232 System, Multi-Drop RS-232 Networks.
