-40 TO85oC,0 TO70oC COMPATIBLEWITH MAX232 AND MAX202
DESCRIPTION
The ST232 isa2 driver,2 receiver device
following EIA/TIA-232 and V.28 communication
standard.Itis particularly suitable for applications
where ±12Vis not available. The ST232 usesa
single 5V power supply and only four external
capacitors (0.1μF). Typical applications are in:
Portable Computers, Low Power Modems,
Interfaces Translation, Battery Powered RS-232
System, Multi-Drop RS-232 Networks.
