RS-232 port with 5 drivers and 3 receivers — the non-standard ratio that fits DTE with full handshaking
The Texas Instruments TRS3238EIPWR is a full-duplex RS-232 transceiver in a 28-TSSOP package, carrying five line drivers and three line receivers. 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.
