SN74AS574N

Flip Flops Overview

The SN74AS574N is an octal D-type edge-triggered flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the AS logic series and features a non-inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 9 ns, a high-level output current of -15 mA, and a low-level output current of 48 mA. It supports TTL input types and is housed in a 20-pin PDIP package for through-hole mounting. The component functions across a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops on a single chip.
• Three-state outputs allow direct connection to bus systems without additional interface hardware.
• Advanced Schottky (AS) technology ensures fast switching speeds with reduced power dissipation compared to standard logic families.

Flip Flops Applications

• High-speed data storage registers in digital systems
• Bus-oriented memory mapping applications
• Parallel-to-serial conversion circuits

Flip Flops Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the procurement channel provides valid traceability records. Check for compliance with relevant environmental standards such as RoHS requirements specified in the product datasheet. Ensure the supplier can provide original factory packaging to prevent handling damage during transit.

Flip Flops Selection Notes

Select this component when design requirements demand high-speed performance combined with moderate power consumption. The AS series offers faster propagation delays than LS or HC equivalents while maintaining lower power than older ALS variants. Consider the 3-state output capability if the design requires shared bus architectures. Verify that the operating temperature range meets the specific environmental conditions of the target application.

Flip Flops Part Context

This component is part of the Texas Instruments SN74AS574 family, which utilizes Advanced Schottky technology. The family includes variations such as the SN74AS574DWR in SOIC packages. These devices are designed for high-performance digital logic applications requiring reliable edge-triggered data storage with tri-state control capabilities.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74AS574DWRE4 and SN74AS574DWRG4. Note that these substitutes utilize different package types (SOIC vs PDIP) and require appropriate footprint adjustments during replacement.
