This means the manufacturer no longer produces the part, and it is not recommended for new designs. Existing BOM lines relying on this order code must source through independent distribution or consider a replacement. For procurement teams managing a legacy BOM, the part is available to quote against an RFQ through surplus and broker channels. ## Key ratings and what they mean for the BOM The LM75CIMM-3/NOPB is a digital local temperature sensor with an I2C output. It measures its own die temperature, not a remote diode — the local-only sensing means the sensor must be placed near the heat source of interest on the PCB. The ±2°C figure is the one to budget for in a thermal monitoring application; the ±3°C worst-case matters for safety-limit thresholds where the absolute maximum error must be accounted for. Resolution is 9 bits, which gives a temperature step of 0.5°C per LSB. This is adequate for system-level thermal monitoring (over-temperature alerts, fan control) but not for fine-grain thermal profiling where 0.125°C or better is needed. The I2C interface operates at the same supply voltage, so the bus pull-up resistors must be referenced to the same rail. The device is offered in an 8-TSSOP or 8-MSOP package (0.118-inch width, 3.00 mm) and the supplier device package is listed as 8-VSSOP. These are functionally identical footprints — the 8-VSSOP is the TI-specific designation for the MSOP package. The 0.65 mm pin pitch is standard for this package family. Mounting is surface-mount only. CT is for prototyping or small-batch builds. ## Features for system integration The sensor includes an Output Switch, Programmable Limit, and Shutdown Mode. The programmable limit allows setting a temperature threshold; when exceeded, the OS (Output Switch) pin asserts an interrupt or alert signal. Shutdown Mode reduces power consumption when temperature monitoring is not needed — useful in battery-powered or duty-cycled systems.","metaTitle":"Texas Instruments LM75CIMM-3/NOPB Digital Temp Sensor, I2C","metaDescription":"Texas Instruments LM75CIMM-3/NOPB digital local temperature sensor, I2C output, ±2°C accuracy, -55°C to 125°C range.
