Flip Flops Procurement Notes

Verify the complete part number including suffixes such as 'E4' to ensure correct RoHS compliance and lead-free status. Confirm that the SOIC-24 package matches your PCB footprint requirements. Check for any recent product change notifications or lifecycle status updates directly from Texas Instruments documentation before finalizing procurement plans.

Flip Flops Selection Notes

Select this component when designing systems requiring dual 4-bit storage with asynchronous clearing capabilities. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range and considers the 30 MHz maximum frequency limit. Verify that the load capacitance requirements do not exceed the specified 50 pF limit for reliable signal integrity at high speeds.

Flip Flops Part Context

This device belongs to the SN74ALS family, known for advanced low-power Schottky technology. It offers improved speed and power consumption characteristics compared to standard LS logic. The SN74ALS874 variant specifically provides dual 4-bit functionality, making it efficient for space-constrained designs requiring multiple flip-flops in a single package.
