Full-duplex operation at 20 Mbps requires matched termination at both ends of the cable — the driver's rise time is fast enough that unterminated stubs cause reflections that exceed the hysteresis band and produce bit errors. The 8-SOIC footprint (3.90 mm width) fits a standard SOIC-8 layout with the termination resistors placed within 10 mm of the pins. ## Active production — no end-of-life watch needed The base product number 65HVD74 covers the wider family; the DR suffix denotes the 8-SOIC package on tape-and-reel or cut-tape. No pin-compatible second-source is listed in the official record, but the 3.3 V full-duplex RS-485 space has several functional equivalents from other vendors — confirm the BOM's exact supply voltage and data-rate requirement before substituting.","metaTitle":"SN65HVD74DR RS-485/422 Transceiver, 20 Mbps, Full Duplex","metaDescription":"Active-production SN65HVD74DR from Texas Instruments.

Outside the family, several 3.3 V full-duplex RS-485 transceivers from other manufacturers are functionally equivalent but require a pinout check — the SN65HVD74DR uses the standard SOIC-8 pinout for full-duplex RS-485, which is not universal across all vendors."},{"question":"What compliance documentation does Texas Instruments provide for SN65HVD74DR?","answer":"The SN65HVD74DR is RoHS3 compliant.
