SN74AS574DWR

Flip Flops Overview

The SN74AS574DWR is an octal D-type edge-triggered flip-flop with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 9 ns. The device provides high drive capability with a low-level output current of 48 mA and a high-level output current of -15 mA. Designed for surface-mount applications, it is housed in a 20-SOIC package and supports a commercial operating temperature range from 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops within a single integrated circuit
• Three-state outputs enabling direct bus-driven wiring connections without additional interface hardware
• High-speed AS logic series performance optimized for demanding digital timing requirements

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching operations in microprocessor-based systems
• Register arrays for temporary data storage in digital logic designs

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging format intended for automated assembly processes. Ensure that the component meets RoHS compliance standards required for your manufacturing environment. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when high-speed switching characteristics are critical for system performance. The AS series offers faster propagation delays compared to standard TTL or AC families. Consider the 48 mA sink current capability for driving heavy loads directly. Verify that the 4.5 V minimum supply voltage aligns with your system power architecture.

Flip Flops Part Context

This device belongs to the Texas Instruments SN74AS logic family, which represents advanced Schottky technology designed for high-speed applications. It shares pin compatibility with other 574-series devices but differs significantly in speed and drive strength specifications. The SOIC-20 package allows for compact printed circuit board layouts while maintaining robust electrical performance standards.

Flip Flops Replacement Considerations

SN74AS574DWRE4 and SN74AS574DWRG4 are confirmed equivalent variants with identical functional specifications.
