Texas Instruments TRS3318E 2.5-V 460-Kbps RS-232 Transceiver With +/-15-kV ESD Protection TRS3318EIPW

The TRS3318EIPW is a dual-driver, dual-receiver RS-232 transceiver designed to operate at a data rate of 460 kbps. It features robust electrostatic discharge (ESD) protection, rated at ±15 kV for the Human-Body Model and ±8 kV for contact discharge, making it suitable for applications requiring high reliability in harsh environments. The device operates from a single supply voltage ranging from 2.25 V to 3 V and incorporates a low-dropout driver output stage, allowing for compatibility with standard RS-232 levels. The TRS3318EIPW includes an auto-powerdown feature that reduces supply current to 1 µA when inactive, enhancing power efficiency, particularly in battery-powered applications. It is packaged in a 20-pin TSSOP format and is designed to be interchangeable with other industry-standard '3318 devices. This transceiver is suitable for various applications, including handheld equipment, PDAs, and cellular phones, where space and power efficiency are critical.
