Operating temperature covers -40°C to 85°C — industrial grade, suited for outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics that see thermal cycling. ## Lifecycle and supply posture The DS1374C-33# carries an Active product status and is ROHS3 compliant.","metaTitle":"Maxim DS1374C-33# RTC Binary Counter, I²C, 16-SOIC","metaDescription":"Maxim DS1374C-33# I²C binary counter RTC in 16-SOIC. 2.97V-5.5V supply, alarm, watchdog, trickle-charger. -40°C to 85°C.

The timekeeping current maxes out at 175 µA, so backup runtime depends on the capacity of the attached battery or capacitor."},{"question":"What is the DS1374C-33# equivalent or substitute?","answer":"Within the same Maxim (now Analog Devices) family, the DS1374U-33+ is a functionally similar binary-counter RTC in a smaller µSOP-10 package — not pin-compatible due to the different footprint and pin count. For a drop-in replacement, stick with the DS1374C-33# in 16-SOIC wide; no direct second-source from another manufacturer is listed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS1374C-33","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS1374C-33 when reusing this data.
