Obsolete — what that means for your BOM line
Texas Instruments lists the LM75CIMM-5/NOPB as Obsolete. That means TI no longer manufactures this specific order code. For an existing BOM position, the part is sourced through independent distribution — we quote to order against your quantity, with availability confirmed at RFQ time.
Key specs that govern the fit
This is a digital local temperature sensor with an I2C output and 9-bit resolution. The sensing range covers -55°C to 125°C, matching the full operating temperature of the device itself. Accuracy is rated ±2°C typical, ±3°C worst-case across the full temperature range. For a system monitoring ambient or board temperature, that ±2°C window is tight enough to flag overtemperature events without false trips — but if your design needs ±1°C or better, this part is not the fit.
Features that matter on the bench
The part includes an output switch, programmable temperature limit, and shutdown mode. The programmable limit lets you set a threshold that asserts the OS output pin — useful as a hardware interrupt to a microcontroller without polling the I2C bus. Shutdown mode drops power consumption when the sensor is not actively measuring.
