SN74LS73ANE4

Flip Flops Overview

The SN74LS73ANE4 is a dual J-K flip-flop from the Texas Instruments SN74LS series, housed in a 14-pin PDIP package. It features negative-edge triggering and includes independent clear inputs for each flip-flop. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a maximum propagation delay of 20 ns at 5 V with a 45 pF load, a clock frequency of 45 MHz, and a static current of 6 mA. Output currents are specified as 400 µA for high level and 8 mA for low level.

Flip Flops Feature Summary

Flip Flops Procurement Notes

Verify the component authenticity by checking the manufacturer marking and date code against official Texas Instruments documentation. Ensure the 14-pin DIP physical dimensions match standard specifications. Confirm RoHS compliance status if required for specific manufacturing environments. Cross-reference the part number suffix 'E4' to ensure it aligns with the intended lead-free packaging requirements.

Flip Flops Selection Notes

Select this component when a dual J-K configuration with negative-edge triggering is required. It is suitable for designs operating strictly at 5 V logic levels. Consider the 45 MHz clock limit and 20 ns propagation delay for timing constraints. This part is appropriate for through-hole assembly processes requiring robust TTL-compatible interfaces.

Flip Flops Part Context

This device belongs to the SN74LS family, known for Low-power Schottky TTL performance. It serves as a fundamental building block for sequential logic circuits. The SN74LS73AN variant shares identical functionality but may differ in packaging or environmental certifications. It is widely used in legacy digital systems requiring reliable data storage and transfer capabilities.

Flip Flops Replacement Considerations

The SN74LS73AN is a direct functional substitute with identical pinout and electrical characteristics. Verify that any replacement maintains the same 14-pin PDIP form factor and through-hole mounting requirements to ensure mechanical compatibility.
