UM3232EESE Description

Short technical summary and product information.

The UNION UM3232EESE is a 3.3V powered RS-232 transceiver designed for portable and hand-held applications. It features two drivers and two receivers, providing robust communication capabilities.

Key electrical specifications include a wide supply voltage range of 3.0V to 5.5V and a minimum transmission rate of 250kbps. The device boasts enhanced ESD protection, with ratings of ±16kV for Human Body Mode, ±15kV for IEC61000-4-2 air discharge, and ±8kV for IEC61000-4-2 contact discharge on transmitter outputs and receiver inputs. Logic I/O pins are protected to ±2kV HBM.

This transceiver meets true EIA/TIA-232-F standards and can operate at EIA/TIA-562 levels with supply voltages as low as 2.7V. It also offers a guaranteed maximum slew rate of 30V/µs and latch-up performance exceeding 200mA.

The UM3232EESE is available in various package types including SOP16, DIP16, TSSOP16, and SSOP16. The SOP16 variant is supplied on a 13-inch tape and reel with a standard package quantity of 2500 pieces. Its small footprint and low-profile packaging contribute to board space savings.
