The -40°C to 125°C operating temperature range covers industrial enclosures, engine-bay ambient, and outdoor telecom cabinets without a temperature grade downgrade. Input offset voltage is specified at 6 mV max at 5 V — adequate for general-purpose threshold detection where the hysteresis band can be set externally to mask the offset. ## SOT-23-5 package and active lifecycle for production runs Housed in a 5-lead SOT-23-5 (SC-74A) package, the TS3021AILT fits into tight PCB layouts and can be hand-soldered with a fine-tip iron — no hot-air station required for rework in the field.","metaTitle":"STMicroelectronics TS3021AILT Comparator, Push-Pull, 105ns","metaDescription":"STMicroelectronics TS3021AILT general-purpose comparator, push-pull output, 105ns propagation delay, 90µA quiescent, 1.8-5V supply, SOT-23-5.
