Datasheet ICL3207 Low Power, +3V to +5.5V, 250kbps, RS-232 Transmitter/Receiver The ICL3207 is a 3.0V 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 15kV ESD protected (Human Body Model) ICL3207 features five transmitters and three receivers. Targeted applications are ISDN 5V lower power replacement for the MAX207, Terminal Adapters (TAs), PDAs, Palmtops, HIN207, and HIN237 peripherals, and notebook and laptop computers Meets EIA/TIA-232 and V.28/V.24 specifications where the low operational power and even lower at 3V standby power consumption is critical. Small footprint packaging and the use of small, low value capacitors Latch-up free ensure board space savings. Data rates greater than On-chip voltage converters require only four 250kbps are ensured at worst case load conditions. external 0.1F capacitors The ICL3207 is fully compatible with 3.3V only Receiver hysteresis for improved noise immunity systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. The ICL3207 is a lower power, Ensured minimum data rate: 250kbps pin-for-pin replacement for the MAX207, HIN207, and Ensured minimum slew rate: 6V/s HIN237. Wide power supply range: Single +3V to +5.5V Table 1 summarizes the features of the ICL3207. AN9863 summarizes the features of each device in Applications the ICL32xx 3V family.
