Datasheet ICL3207E 15kV ESD Protected, +3V to +5.5V, Low Power, 250kbps, RS-232 Transmitter/Receiver The ICL3207E is a 3V to 5.5V powered RS-232 Features transmitter/receiver that meets ElA/TIA-232 and Pb-free (RoHS compliant) V.28/V.24 specifications, even at V = 3.0V. The CC ESD protection for RS-232 I/O pins to 15kV ICL3207E features five transmitters and (IEC61000) three receivers. It provides 15kV ESD protection (IEC61000-4-2 Air Gap) and 15kV Human Body 5V lower power replacement for MAX207E, Model protection on transmitter outputs and receiver HIN207E, and HIN237E inputs (RS-232 pins). Targeted applications are ISDN Meets EIA/TIA-232 and V.28/V.24 specifications Terminal Adapters (TAs), PDAs, Palmtops, at 3V peripherals, and notebook and laptop computers where the low operational power consumption and Latch-up free even lower standby power consumption is critical. On-chip voltage converters require only four Small footprint packaging and the use of small, low external 0.1F capacitors value capacitors ensure board space savings. Data RS-232 compatible with V = 2.7V rates greater than 250kbps are ensured at worst case CC load conditions. The ICL3207E is fully compatible with Receiver hysteresis for improved noise immunity 3.3V only systems, mixed 3.3V and 5V systems, and Ensured minimum data rate: 250kbps 5V only systems. The ICL3207E is a lower power, pin-for-pin replacement for the MAX207E, HIN207E, Ensured minimum slew rate: 6V/s and HIN237E. Wide power supply range: Single +3V to +5.5V Table 1 summarizes the features of the ICL3207E. Applications AN9863 summarizes the features of each device in the ICL32xxE 3V family.
