SN74LS74ADRG4

Flip Flops Overview

The SN74LS74ADRG4 is a dual positive-edge-triggered D-type flip-flop from Texas Instruments' 74LS series. It features independent Set and Reset inputs with active-low logic levels. The device operates within a supply voltage range of 4.75V to 5.25V, supporting a maximum clock frequency of 33 MHz. Key electrical parameters include a propagation delay of 40 ns at 5V with 15pF load, a high-level output current of -400 µA, and a low-level output current of 8 mA. It is housed in a 14-SOIC surface-mount package.

Flip Flops Feature Summary

• Dual configuration containing two independent D-type flip-flops
• Positive-edge triggering mechanism for data capture
• Active-low asynchronous Set and Reset control inputs

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register construction
• Basic digital memory storage elements

Flip Flops Procurement Notes

Verify the specific ordering suffix 'RG4' against the manufacturer's official documentation to confirm RoHS compliance status and tape-and-reel packaging specifications. Ensure that the component designation matches the exact datasheet revision required for your design. Cross-reference the pinout diagram with your PCB layout to prevent orientation errors during assembly.

Flip Flops Selection Notes

Select this component when a standard TTL-compatible logic family is required for designs operating strictly at 5V. The LS series offers lower power consumption compared to standard 74-series counterparts while maintaining compatible logic thresholds. Consider the SOIC package dimensions for board space constraints and verify thermal dissipation requirements for the specific application environment.

Flip Flops Part Context

This part belongs to the widely adopted 74LS (Low-power Schottky) logic family, known for balancing speed and power efficiency. The SN74LS74ADR variant represents the standard commercial-grade version, while the ADRG4 suffix indicates specific manufacturing and environmental compliance attributes defined by Texas Instruments for mass production.

Flip Flops Replacement Considerations

The SN74LS74ADRE4 is a confirmed equivalent part number representing the same functional device with alternative manufacturing or compliance suffixes.
