SN74LS74AN-NG

Flip Flops Overview

The SN74LS74AN-NG is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments. It features two independent circuits within a single package, each equipped with preset and clear inputs for direct control of the output state. The device operates on a standard TTL logic family, utilizing a 14-pin PDIP (Plastic Dual In-line Package) suitable for through-hole mounting. It supports a supply voltage range of 4.5 V to 5.5 V and functions within an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual independent D-type flip-flop configuration
• Positive-edge triggering mechanism
• Direct preset and clear input functionality

Flip Flops Applications

• Digital data storage applications
• Shift register construction
• Frequency division circuits

Flip Flops Procurement Notes

Verify that the specific suffix 'NG' aligns with your required packaging or material specifications, as datasheets may primarily reference the base part number SN74LS74AN. Confirm the manufacturer source is Texas Instruments or an authorized distributor to ensure component authenticity. Check RoHS compliance status if environmental regulations apply to your assembly process. Ensure the PDIP-14 package matches your PCB footprint requirements before finalizing procurement.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with active high preset and clear inputs is required for TTL-compatible digital systems. The LS series offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the through-hole PDIP package if prototyping or legacy board designs necessitate manual soldering or socket usage. Evaluate the 18 ns propagation delay against system timing constraints to ensure adequate performance margins.

Flip Flops Part Context

This component belongs to the SN74LSxx series of logic integrated circuits from Texas Instruments. The SN74LS74AN variant specifically provides two edge-triggered D flip-flops in a 14-lead plastic DIP package. It is designed for compatibility with standard transistor-transistor logic (TTL) systems, offering reliable operation for sequential logic tasks such as memory elements and counters in digital electronics.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74LS74N and SN74LS74AP from Texas Instruments, which share identical logical functionality and pinout configurations. Other manufacturers offer equivalent parts under different naming conventions, such as the MC74LS74P from ON Semiconductor. Verify that any replacement maintains the same PDIP-14 package and TTL input/output characteristics to ensure seamless integration.
