CY74FCT827CTSOC

Overview

The CY74FCT827CTSOC is a ten-bit buffer and line driver from the FCT logic series, manufactured by Texas Instruments. It features non-inverting outputs with three-state capability housed in a 24-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 14 ns, high-level output current of -32 mA, and low-level output current of 64 mA. Static current is specified at 100 uA, with a maximum operating temperature of +85 C.

Feature Summary

• Provides ten-channel buffering with three-state output control for bus-oriented systems
• Features CMOS technology compatible with TTL input levels
• Offers high drive capability suitable for driving transmission lines

Applications

• Bus-oriented memory architectures
• Clock drivers
• Buffering applications requiring high fan-out

Procurement Notes

Verify the complete part number including suffixes such as 'CTSOCT' versus 'CTSOC' to ensure correct packaging configuration. Confirm RoHS compliance status through official documentation. Check for specific tape and reel or cut tape requirements based on assembly needs. Validate that the supplier provides genuine Texas Instruments components with traceable lot codes.

Selection Notes

Select this component when ten independent buffered channels are required with three-state isolation. Ensure the system operates within the 4.75 V to 5.25 V supply range. Consider the 14 ns propagation delay for timing constraints. Verify that the SOIC-24 package fits the PCB layout. Compare against other FCT family members if fewer channels or different drive strengths are needed.

Part Context

This part belongs to the CY74FCT827T series of high-speed CMOS buffers. It is designed for applications requiring fast switching speeds and low power consumption. The FCT series bridges the performance gap between standard TTL and advanced CMOS technologies. It is commonly used in digital signal processing and data communication systems.

Replacement Considerations

Check for direct substitutes within the same FCT family offering identical pinouts and electrical characteristics. Verify compatibility with existing board designs before substitution.
