SP232EEN-EV

Drivers, Receivers, Transceivers Overview

The EVVO SP232EEN-EV is a dual driver and dual receiver RS-232 line transceiver designed for serial communication applications. It operates from a single +5V power supply and meets EIA/TIA-232-D and ITU V.28 specifications. The device supports data rates up to 120kbps under load conditions. It features low power CMOS technology with a typical operating current of 3mA and includes a shutdown mode that reduces supply current to less than 1µA. The component is housed in a 16-pin NSOIC package and functions within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation on the component marking to confirm EVVO origin, as this part number follows industry-standard naming conventions often used by multiple foundries. Ensure the suffix matches the required tape-and-reel or tube packaging configuration specified in the official datasheet. Cross-reference the pinout and electrical characteristics with the specific EVVO datasheet to guarantee compatibility with the target design requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a standard RS-232 transceiver is needed for 5V logic systems. It is suitable for designs prioritizing low standby power due to the shutdown feature. Verify that the system environment requires the specified industrial temperature range and that the 120kbps data rate meets the application's throughput needs. Confirm that the NSOIC-16 package fits the available PCB footprint constraints.
