CY74FCT2574CTSOCT

Overview

The CY74FCT2574CTSOCT is an octal D-type register with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features a propagation delay of 6.5 ns. The device provides high-level output current of -15 mA and low-level output current of 12 mA. It is housed in a SOIC-20 package and supports non-inverting logic polarity.

Feature Summary

• Incorporates 25-ohm output series resistors to reduce transmission-line reflection noise
• Functionally and pinout compatible with FCT and F Logic families
• Provides registered storage for octal data bus applications

Applications

• High-speed data bus buffering
• System memory interface registration
• Clocked data storage in digital circuits

Procurement Notes

Verify the specific suffix 'CTSOCT' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging and temperature grade. Ensure compatibility with existing board layouts, as this component utilizes a standard SOIC-20 footprint. Cross-reference the manufacturer part number directly with the datasheet to avoid substitution errors due to minor suffix variations.

Selection Notes

Select this component when registered octal data storage with 3-state outputs is required. It is suitable for designs needing compatibility with FCT logic standards. Consider the 6.5 ns propagation delay and 25-ohm series resistors for signal integrity management in high-speed bus systems operating at 5 V.

Part Context

This part belongs to the CY74FCT2574T family of octal D-type registers. It is designed for high-speed CMOS applications requiring registered bus holding capabilities. The device integrates internal pull-up resistors and offers robust drive characteristics suitable for driving multiple loads on a shared data bus architecture.

Replacement Considerations

Check for direct equivalents within the CY74FCT2574T series or other FCT-compatible octal registers from Texas Instruments. Verify that any substitute maintains the same SOIC-20 package and electrical specifications.
