DS1374U-33+T&R

Real Time Clock Overview

The DS1374U-33+T&R is a real-time clock (RTC) IC featuring a 32-bit binary counter for continuous timekeeping and an additional 24-bit counter configurable as a watchdog timer, alarm generator, or non-volatile RAM. It utilizes an I²C serial interface for programming and includes automatic power-fail detection with seamless switching to a backup supply. The device supports trickle charging for rechargeable backup sources and provides separate interrupt and square-wave outputs. Operating within a voltage range of 2.97V to 5.5V, it is housed in a 10-pin µSOP package and functions across a temperature range of -40°C to +85°C.

Real Time Clock Procurement Notes

Verify the specific suffix '+T&R' indicates tape-and-reel packaging when sourcing this component. Confirm that the 'U' designation corresponds to the 10-pin µSOP package variant rather than the SOIC option. Ensure compatibility with standard I²C bus levels and check for RoHS compliance documentation associated with the lead-free marking.

Real Time Clock Selection Notes

Select this model for applications requiring a simple binary counter RTC with integrated watchdog functionality. The 3.3V nominal voltage rating suits systems operating between 2.97V and 5.5V. Consider the 10-pin µSOP package for space-constrained designs. Verify that external 32.768kHz crystal requirements align with the internal oscillator's 6pF load capacitance specification.

Real Time Clock Part Context

This part belongs to the DS1374 family of real-time clocks from Analog Devices/Maxim Integrated. The 'U' suffix denotes the 10-pin µSOP package, while '33' specifies the 3.3V operating voltage range. The '+' indicates a lead-free/RoHS-compliant version. Other variants include the 16-pin SO package (DS1374C) and different voltage options like DS1374U-18+.
