CD74FCT827CTM

Overview

The CD74FCT827CTM is a single 10-bit buffer and line driver manufactured by Harris Corporation, belonging to the FCT/PCT-CMOS logic family. It features a 24-pin plastic Small Outline Package (SOP) with a maximum low-level output current of 0.048 A and a load capacitance of 50 pF. The device operates within a temperature range of -40 °C to 85 °C and requires a 5 V power supply. Its outputs are three-state with true polarity, controlled by an active-low enable signal.

Feature Summary

• Provides non-inverting buffering for ten independent data lines simultaneously.
• Features three-state outputs that allow connection to shared bus structures without electrical conflict.
• Incorporates Schmitt Trigger inputs on all channels to filter noisy signals and ensure clean switching transitions.

Applications

• High-speed clock distribution networks requiring signal regeneration.
• Bus-oriented memory architectures utilizing parallel data paths.
• General-purpose digital signal buffering in industrial control systems.

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status as indicated in specifications, noting potential lead-based solder options. Validate package dimensions against SOP-24 standards and check operating temperature ratings for specific environmental requirements before procurement.

Selection Notes

Select this component when driving high-capacitance loads or long traces in 5V CMOS environments. The FCT technology offers faster propagation speeds compared to standard 74HC series devices. Ensure the design accommodates the 50 pF load capability and utilizes the active-low enable pin for proper bus arbitration.

Part Context

Harris Corporation was a prominent semiconductor manufacturer acquired by Renesas Electronics. This part represents legacy FCT logic technology designed for high-performance digital applications. While production may have transitioned, the datasheet parameters remain valid for existing designs utilizing Harris-sourced components.

Replacement Considerations

Cross-reference with Texas Instruments CY74FCT827 variants for pin-compatible alternatives. Verify voltage levels and package types match exactly. Note that newer generations may offer improved RoHS compliance while maintaining functional equivalence.
