Product details

Binary counter RTC with I²C — what it is and where it fits

The part integrates an alarm comparator, a programmable square-wave output, a trickle-charger for backup supercap or battery, and a watchdog timer — four features that eliminate external supervisor ICs in many designs. 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.

Frequently asked questions

Does the DS1374C-33# support battery backup?

Yes, it includes a dedicated battery-backup input (VBAT) that accepts 1.3V to 5.5V, plus an integrated trickle-charger for recharging a supercap or secondary cell. The timekeeping current maxes out at 175 µA, so backup runtime depends on the capacity of the attached battery or capacitor.

What is the DS1374C-33# equivalent or substitute?

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.
