NRND — plan the BOM transition now
Texas Instruments lists the LM75BIM-5 as NRND (Not Recommended for New Designs). This means the part remains available for existing production but is not intended for new board spins.
The LM75BIM-5 delivers ±2°C typical accuracy across its -55°C to 125°C operating range, with a worst-case ±3°C over the full temperature sweep. That ±2°C figure holds from -25°C to 100°C — the band most thermal-management loops actually regulate within. For a fan-speed controller or over-temperature alarm, the ±3°C guard band at the extremes still keeps the system inside the silicon junction limits. The 9-bit resolution gives 0.5°C per LSB — adequate for board-level thermal monitoring where 1°C granularity is the practical decision threshold.
I²C digital output with programmable limit and shutdown
The sensor communicates over a standard I²C interface — two wires (SDA, SCL) plus the OS (overtemp shutdown) output pin. The programmable limit register lets the OS pin assert when the local temperature crosses a threshold you set, without polling the bus. Shutdown mode drops the supply current to a few microamps for battery-powered intervals between reads. Housed in an 8-pin SOIC (0.154" wide, 3.90 mm body), the LM75BIM-5 footprint matches the industry-standard LM75 pinout. The tube packaging means it ships in antistatic tubes of 95 or 100 units — not tape-and-reel, so plan for manual placement or tube-fed pick-and-place.
