It operates from a 3V to 5.5V supply. Data rate is rated at 400 kbps. The receiver hysteresis is specified at 300 mV. Temperature range spans -40°C to 85°C, covering industrial control panels, outdoor telecom cabinets, and factory-floor serial ports. The 28-TSSOP footprint is a common 4.40 mm body width, compatible with standard SOIC-28 land patterns after adjusting for the finer pitch. ## Supply flexibility — one part for 3.3V and 5V rails The 3V to 5.5V supply range means the same BOM line works across a mixed-voltage system. The wide supply tolerance also helps with unregulated rails. ## Active lifecycle — no end-of-life pressure for new designs The TRS3238EIPWR carries an active product status from Texas Instruments. This part can be specified into production without an obsolescence watch for the foreseeable future. ROHS3 compliance is confirmed, so it passes EU and global material restrictions without an exemption expiry concern.","metaTitle":"TRS3238EIPWR RS-232 Transceiver, 5/3 Drivers, 400 kbps","metaDescription":"TI TRS3238EIPWR full-duplex RS-232 transceiver with 5 drivers and 3 receivers. 400 kbps data rate, 3V to 5.5V supply, -40°C to 85°C.
