It uses three lines: a clock, a bidirectional data line, and a chip-select reset. The One-Shot feature lets you initiate a single conversion and read the result, then the sensor goes into a low-power state until the next command. This cuts average supply current significantly in systems that only need temperature data every few seconds — think battery-backed data loggers or wireless sensor nodes. ## Lifecycle and sourcing The DS1620S+T&R carries an Active lifecycle status and is ROHS3 compliant. It remains a viable BOM line for both new designs and production spares.","metaTitle":"DS1620S+T&R Digital Temperature Sensor, ±0.5°C, 8-SOIC","metaDescription":"DS1620S+T&R digital local temperature sensor, ±0.5°C accuracy, -55°C to 125°C range, 3-wire interface, 8-SOIC.
