The surface-mount assembly is standard reflow; no special underfill is required for most portable applications. Operating temperature is -40°C to 125°C with the sensor tested at -10°C to 100°C and -40°C to 125°C conditions. ## Active lifecycle and compliance Texas Instruments lists no pin-compatible second source or direct successor for this order code. If you are evaluating a BOM hedge, the SMAART Wire protocol is TI-proprietary, so a drop-in alternate from another vendor is unlikely — the design is locked to this interface unless you add a protocol translator.","metaTitle":"TMP144YFFT Texas Instruments Digital Temp Sensor","metaDescription":"TMP144YFFT digital local temp sensor, ±1°C accuracy, -40 to 125°C, 1.4-3.6V supply, SMAART Wire UART output, 4-DSBGA.
