Renesas Electronics Corporation Drivers, Receivers, Transceivers ISL4223EIRZ

The ISL4223EIRZ is a dual driver and dual receiver RS-232 transceiver designed for low power applications. It operates within a voltage range of +2.7V to +5.5V and is compliant with EIA/TIA-232 and V.28/V.24 specifications, even at a supply voltage of 3V. The device features ±15kV ESD protection on its I/O pins, ensuring robust performance in electrically noisy environments. With a guaranteed data rate of 250kbps, the ISL4223EIRZ is suitable for applications requiring reliable serial communication, such as handheld devices, PDAs, and portable equipment. The transceiver is packaged in a compact 5mm x 5mm QFN format, which is 40% smaller than traditional 20-lead TSSOP packages, making it ideal for space-constrained designs. Additionally, it incorporates on-chip voltage converters that require only four external 0.1µF capacitors, and it supports both manual and automatic powerdown features, reducing supply current to 150nA in standby mode. This combination of features makes the ISL4223EIRZ a suitable choice for engineers looking for a compact, low-power RS-232 solution.
