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.
Lifecycle and compliance — active, ROHS3
The MAX1489EESD+ is listed as Active in production with ROHS3 compliance. This is a mature, stable part — no supply-chain surprises expected for new designs or ongoing production.
