SN74ALS374ADW

Flip Flops Overview

The SN74ALS374ADW is an octal D-type edge-triggered flip-flop from the Texas Instruments 74ALS series, housed in a 20-pin SOIC package. It features three-state outputs and operates within a supply voltage range of 4.5V to 5.5V. The device exhibits a maximum propagation delay of 16ns at 5V with 50pF load, supporting clock frequencies up to 35MHz. Output drive capabilities include -2.6mA high-level and 24mA low-level current. Static current consumption is specified at 19mA, with an operating temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops in a single integrated circuit
• Three-state output architecture enabling direct bus interfacing and system-wide data line management
• Non-inverting logic function ensuring positive edge triggering for precise synchronous data capture

Flip Flops Applications

• Parallel-to-serial data conversion circuits requiring temporary storage buffers
• High-speed digital signal processing systems utilizing 8-bit data word alignment
• Memory address latching applications in microprocessor-based control architectures

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes such as E4 or G4 for lead-free requirements. Ensure packaging specifications match design constraints, noting that tape-and-reel options may differ from tube quantities. Cross-reference datasheet revisions to validate electrical characteristics against current production standards.

Flip Flops Selection Notes

Select this component when designing systems requiring fast switching speeds within the ALS logic family constraints. Consider the 20-pin SOIC footprint for surface-mount assembly compatibility. Evaluate power dissipation limits given the 19mA static current draw under standard operating conditions. Ensure input voltage levels align with TTL-compatible signaling requirements for reliable interface integration.

Flip Flops Part Context

This part belongs to the broader 74ALS374 family, which includes variants like SN74ALS374ANSR and SN74ALS374ADWR. These components share identical logical functionality but differ in packaging formats and reel specifications. The ADW designation specifically indicates a wide-body SOIC package suitable for automated surface-mount placement processes.

Flip Flops Replacement Considerations

Direct substitutes include SN74ALS374ADWR and SN74ALS374ANSR, which maintain functional equivalence. Verify pinout compatibility and thermal performance characteristics before substitution. Check for updated environmental compliance markings associated with suffix variations.
