Product details

RS-232 transceiver with dual-rail supply and 500 mV hysteresis

The AD231AR is a full-duplex RS-232 transceiver with two drivers and two receivers, housed in a 16-SOIC surface-mount package. It is part of the AD231 series and operates over the industrial temperature range of -40°C to 85°C, making it suitable for factory automation, outdoor telecom, and instrumentation panels where serial communication must survive thermal cycling. Receiver hysteresis is 500 mV.

RoHS non-compliance — plan for exemptions or lead-free alternative

RoHS status is non-compliant.

Frequently asked questions

Is AD231AR compatible with 5V logic?

Yes — the logic supply range of 4.5V to 5.5V directly accepts standard 5V CMOS/TTL logic levels without external level shifting.

Is AD231AR equivalent to MAX232?

Both are full-duplex RS-232 transceivers with 2/2 driver/receiver counts, but the AD231AR uses a dual-rail supply (5V logic + 7.5–13.2V charge-pump) versus the MAX232's single 5V supply with internal charge pump. They are not pin-compatible; verify the supply scheme before substituting.

What is AD231AR's listed type and duplex?

The device type is Transceiver, and the duplex mode is Full — it can transmit and receive simultaneously on separate signal pairs.
