ICL3222ECAZ-T

±15kV ESD Protected, +3V to +5.5V, 1μA, 250kbps, RS-232 Transmitters/Receivers

RS-232接口集成电路 RS232 3V 2D/2R 15KV SHTDWN COMEL

The ICL3222ECAZ-T ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E,  and ICL3243E are 3.0V to 5.5V powered RS-232  transmitters/receivers which meet ElA/TIA-232 and  V.28/V.24 specifications, even at VCC = 3.0V.  Additionally, they provide ±15kV ESD protection  (IEC61000-4-2 Air Gap and Human Body Model) on  transmitter outputs and receiver inputs (RS-232 pins).

Features ICL3222ECAZ-T
