Product details

RS-232 transceiver for industrial serial links

It handles asynchronous serial communication up to 1 Mbps, making it a fit for point-to-point or multi-drop RS-232 links in PLCs, motor drives, and sensor interfaces. Supply voltage range of 3 V to 5.5 V allows direct connection to 3.3 V or 5 V logic rails without a separate level shifter — a practical simplification for mixed-voltage backplanes.

Industrial temperature and receiver hysteresis

Receiver hysteresis of 300 mV provides noise immunity on long RS-232 cable runs — the dead zone between switching thresholds prevents chatter from coupled transients on the twisted pair.

Active production and compliance

Standard lead times apply for volume orders. ROHS3 compliant, with no exemption conflicts for EU or California regulatory filings.

Frequently asked questions

Is the SN65C3222EDW RoHS compliant?

Yes, it is ROHS3 compliant per Texas Instruments classification.

What is the closest pin-compatible alternative to the SN65C3222EDW?

Within the same TI family, the SN65C3222E (same 2/2 driver/receiver count, same 20-SOIC footprint) is a direct alternative with identical pinout. Confirm the supply voltage and data rate match your design before substituting.
