ILX207DW
1
Interface IC of data serial transfer with one supply voltage
Interface transceivers of serial data as per RS - 232 MAX207 standard with one
supply voltage and transmitter bipolar output voltage formed by the embedded voltage
multiplication oscillator on 4 external capacitances equal to 0,1mkF, corresponding to
EIA/TIA-232E, V.28 standards, are purposed for application in up-to-date high-
performance calculating systems, high-speed electronic devices with high reliability of
information exchange between remote objects.
Functions:
5 transmitters and 3 receivers of serial data
as per RS - 232 standards
