SN74LS74ANSRG4

Flip Flops Overview

The SN74LS74ANSRG4 is a dual D-type positive-edge-triggered flip-flop from the Texas Instruments SN74LS series. It operates within a supply voltage range of 4.75V to 5.25V and features asynchronous preset and clear inputs that override other inputs when active low. The device utilizes Low-Power Schottky (LS) TTL technology, providing a propagation delay of 40ns. It is housed in a 14-pin TSSOP package with an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual independent D-type flip-flops with positive-edge clock triggering
• Asynchronous preset and clear control inputs for immediate state setting or resetting
• Low-Power Schottky (LS) logic family integration for optimized speed and power consumption

Flip Flops Applications

• Digital data storage and register circuits
• Frequency division and counter stages
• State machine implementation in sequential logic systems

Flip Flops Procurement Notes

Verify the specific suffix 'A' and 'SRG4' against the manufacturer's official documentation to confirm the exact pinout, lead finish, and RoHS compliance status. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement specifications.

Flip Flops Selection Notes

Select this component when designing systems requiring dual D-type latching with asynchronous control using standard 5V TTL logic levels. Consider the LS series characteristics for applications balancing switching speed with moderate power dissipation. Verify that the TSSOP package dimensions align with the available board space and assembly capabilities.
