SN74ALS574BDWR

Flip Flops Overview

The SN74ALS574BDWR is an octal D-type edge-triggered flip-flop from the Texas Instruments ALS logic series. It features eight non-inverting outputs with three-state capability, housed in a 20-pin SOIC package for surface mount applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. Key electrical specifications include a propagation delay of 14 ns, a low-level output current of 24 mA, and a high-level output current of -2.6 mA. It functions reliably across a minimum operating temperature of 0°C.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture providing eight independent data storage elements
• Three-state output configuration enabling direct bus driving and system interconnect flexibility
• Non-inverting polarity ensuring logical consistency between input data and stored output states

Flip Flops Applications

• Register files in digital processing systems
• Bus interface circuits requiring tri-state isolation
• Data storage modules in microprocessor-based designs

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the reel packaging format intended for automated surface-mount assembly. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the datasheet revision to confirm pinout compatibility with existing board layouts before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data latching with minimal propagation delay. The ALS series offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the SOIC-20 footprint constraints and verify that the 24 mA sink current capability meets the load requirements of the connected circuitry.

Flip Flops Part Context

This part belongs to the standard 74ALS logic family, widely utilized for high-speed digital switching applications. The SN74ALS574 variant specifically provides octal storage functionality, distinguishing it from latch variants like the SN74ALS573 which utilize level-sensitive control rather than edge-triggering mechanisms.
