SN74ALS74ADRE4

Flip Flops Overview

The SN74ALS74ADRE4 is a dual D-type flip-flop from Texas Instruments' Advanced Low-Power Schottky (ALS) logic family. It features two independent circuits in a 14-pin SOIC package, operating within a 4.5 V to 5.5 V supply range. The device provides TTL-compatible inputs and outputs, with a typical propagation delay of 18 ns. It supports positive-edge triggering and includes set and reset functions for state control.

Flip Flops Feature Summary

• Dual independent D-type flip-flops integrated into a single surface-mount package
• Advanced Low-Power Schottky technology ensures high-speed operation with reduced power consumption
• TTL-compatible input and output interfaces for direct system integration

Flip Flops Applications

• High-speed digital data storage and buffering applications
• State machine implementation in control logic systems
• Parallel-to-serial or serial-to-parallel data conversion circuits

Flip Flops Procurement Notes

Verify the 'E4' suffix indicates lead-free composition and RoHS compliance per manufacturer specifications. Confirm the SOIC-14 package dimensions match PCB footprint requirements. Ensure the ALS series availability aligns with long-term procurement strategies, as legacy logic families may have limited production runs.

Flip Flops Selection Notes

Select this component when low power dissipation and moderate speed are required for dual flip-flop operations. The ALS series offers faster switching than standard LS logic while consuming less power than AS series devices. Verify that the 18 ns propagation delay meets the timing constraints of the target digital circuit design.

Flip Flops Part Context

This part belongs to the SN74ALS74A family, which contains dual D-type flip-flops. The SN74ALS74ADRE4 is the specific reel-packaged variant of the SN74ALS74AD tube version. Both share identical electrical characteristics and functionality within the Advanced Low-Power Schottky logic category.

Flip Flops Replacement Considerations

The SN74ALS74AD serves as a direct functional equivalent in tube packaging. For LS-series upgrades, the SN74LS74ADR offers similar functionality but with slower speeds and higher power consumption. Cross-family replacements require verification of voltage levels and timing parameters.
