Product details

Data rate and hysteresis — margin on noisy lines

Rated at 120 kbps, this receiver is sized for standard UART speeds. The 1.11 V of hysteresis helps reject noise on unshielded twisted-pair or ribbon cable runs inside a cabinet.

Package and mounting — standard SOIC footprint

Housed in a 14-SOIC narrow-body (0.154" body width, 3.90 mm), surface-mount package. The tube shipping medium is fine for hand-assembly or low-volume production; for high-volume reels, check the tape-and-reel variant.

This is a mature, stable part — no supply-chain surprises expected for new designs or ongoing production.

Frequently asked questions

What is the data rate of MAX1489EESD+?

The maximum data rate is 120 kbps, suitable for standard UART speeds up to 115.2 kbps with margin.

Is MAX1489EESD+ RoHS compliant?

Yes, it is ROHS3 compliant — no restricted substances above the threshold limits.

What is the difference between MAX1489EESD+ and MAX1489EESD?

The '+' suffix indicates ROHS3 compliance on the MAX1489EESD+; the non-plus variant (MAX1489EESD) may not carry the same RoHS rating. Functionally and pin-compatibly they are identical — the '+' is the preferred ordering code for RoHS-sensitive BOMs.

Is MAX1489EESD+ compatible with 5V logic?

Yes. The receiver outputs swing from 0V to 5V (CMOS/TTL levels) when powered from a 5V supply. No external level shifting is needed on the output side.
