The SN65HVD20DRG4: The receiver includes 130 mV of hysteresis to reject noise on the bus.
If your system runs on a 3.3 V bus, this transceiver is out of range; look at the 3.3 V variants in the SN65HVD2x family instead.
If you are still in design, this is not a part to qualify; move to a current-production alternative.
8-pin SOIC with 3.90 mm body width. Surface-mount only.
Determines availability and need for a replacement part.
Critical for design continuity and BOM maintenance when original part is obsolete.
Essential for design engineers to validate PCB layout and compatibility.
Key factor for sourcing buyers comparing costs across distributors.
Immediate sourcing need for procurement to fill BOM lines.
Enables cross-referencing for brokers and engineers finding alternatives.
