Renesas Electronics Corporation Integrated Circuits (ICs) - Interface - Drivers, Receivers, Transceivers ICL3221CA

The ICL3221CA is a low-power RS-232 transceiver designed for operation within a voltage range of +3V to +5.5V, making it suitable for battery-powered and portable applications. It is compliant with EIA/TIA-232 and V.28/V.24 specifications, ensuring reliable communication at data rates up to 250kbps. The device features a low supply current of 1µA in power-down mode, which is beneficial for energy-sensitive designs. The ICL3221CA includes on-chip voltage converters that require only four external 0.1µF capacitors, simplifying the design process. It also offers manual and automatic power-down features, enhancing power efficiency by automatically powering down when peripherals are inactive. The device is RoHS compliant and provides 15kV ESD protection, ensuring durability in various environments. This transceiver is a drop-in replacement for several existing devices, including the MAX3221 and MAX3232, allowing for easy upgrades in existing designs. Its small footprint and compatibility with both 3.3V and 5.0V systems make it versatile for a range of applications, including laptops, modems, and digital cameras.
