SN74LS74ANE4

Flip Flops Overview

The SN74LS74ANE4 is a dual D-type positive-edge-triggered flip-flop from the Texas Instruments SN74LS74A series. It features independent preset and clear inputs that asynchronously set or reset outputs regardless of other input levels. When active-high, data meeting setup time requirements transfers to the output on the clock's positive edge. The device operates within a 4.75 V to 5.25 V supply range, with a propagation delay of 40 ns, -0.4 mA high-level output current, and 8 mA low-level output current. It supports through-hole mounting in a PDIP-14 package across a 0°C to +70°C temperature range.

Flip Flops Feature Summary

• Dual independent D-type positive-edge-triggered flip-flops
• Asynchronous preset and clear control inputs
• TTL-compatible logic family interface

Flip Flops Applications

• Data storage and register circuits
• Shift register configurations
• Frequency division circuits

Flip Flops Procurement Notes

Verify the 'E4' suffix indicates lead-free compliance and RoHS adherence per manufacturer documentation. Confirm the PDIP-14 through-hole package matches your PCB footprint requirements. Ensure the operating voltage remains strictly between 4.75 V and 5.25 V to maintain specified electrical characteristics and prevent device damage.

Flip Flops Selection Notes

Select this component for applications requiring dual D-type flip-flops with asynchronous control. The LS logic family offers standard TTL compatibility. Verify that the 40 ns propagation delay meets system timing constraints. Consider the PDIP-14 package for prototyping or through-hole manufacturing processes where surface mount options are unsuitable.

Flip Flops Part Context

This part belongs to the SN74LS74A series, which contains two independent D-type flip-flops. The SN74LS74ANE4 specifically denotes the lead-free, RoHS-compliant version manufactured by Texas Instruments. It is designed for general-purpose digital logic applications requiring reliable data storage and transfer capabilities within standard TTL voltage ranges.

Flip Flops Replacement Considerations

SN74LS74AN is the non-RoHS equivalent. SN74LS74N is the generic industry counterpart. Cross-referencing with SN54LS74A is possible for military-grade temperature ranges.
