• Features Schmitt trigger inputs and noise filtering for reliable operation on noisy buses

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage in consumer electronics
• Parameter retention in automotive embedded modules

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'OT' denotes the SOT-23 package. Confirm RoHS compliance status as required by your manufacturing standards. Ensure the design accounts for the 2.5V minimum operating voltage. Check for end-of-life notifications or recommended replacement parts due to potential obsolescence.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for low-capacity non-volatile storage. The SOT-23 package offers space efficiency compared to SOIC or PDIP options. Ensure the system voltage remains above 2.5V to maintain full functionality. Consider the 400 kHz speed limit if higher bus throughput is necessary.

Memory IC Part Context

This part belongs to the 24LC04B series of 4-Kbit serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA04 and 24FC04 but differs in operating voltage and speed specifications. The series provides a standardized I²C interface for easy integration into various microcontroller-based designs.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04 variants with different packages such as 24LC04BT-I/SN or 24LC04BH-E/P. Verify that any replacement matches the required temperature grade and package dimensions.
