CY74FCT16827ETPACT

Overview

The CY74FCT16827ETPACT is a 20-bit buffer and line driver from the FCT logic series, manufactured by Texas Instruments. It features non-inverting inputs with three-state outputs housed in a 56-pin TSSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical specifications include a propagation delay of 9 ns at 5 V, high-level output current of -32 mA, and low-level output current of 64 mA. It supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Provides 20-bit buffering capability with non-inverting signal transmission
• Features three-state outputs for effective bus driving and isolation
• Designed for high-speed digital applications with low propagation delay

Applications

• High-density data bus buffering systems
• Clock distribution networks requiring precise timing
• Memory interface circuits for address and data lines

Procurement Notes

Verify the specific suffix ETPACT corresponds to the 56-TSSOP package and tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input pins are tied to valid logic levels when unused to maintain operational stability.

Selection Notes

Select this component for designs requiring 20-channel buffering with strong drive capabilities. The FCT series offers faster switching speeds compared to standard CMOS logic. Verify that the system power supply remains strictly within the 4.75 V to 5.25 V window to ensure correct logic thresholds and prevent damage.

Part Context

This part belongs to the CY74FCT family of fast CMOS logic devices. It serves as a high-performance alternative to older bipolar technologies, offering reduced power consumption while maintaining high-speed operation. The 20-bit width makes it suitable for parallel data paths in complex digital systems.

Replacement Considerations

Direct pin-compatible substitutes may include other 20-bit FCT buffers such as the CY74FCT16827ATPACT or CY74FCT16827CTPACT, differing primarily in speed grades or temperature ratings. Always verify datasheet compatibility before substitution.
