CY74FCT16823CTPACT

Overview

The CY74FCT16823CTPACT is an 18-bit D-type flip-flop bus driver manufactured by Texas Instruments. It features two functional blocks, each handling nine bits with true output polarity. The device utilizes a TSSOP-56 package and operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 12.5 ns at 5 V, low-level output current of 32 mA, and high-level output current of -32 mA. It supports 3-state outputs and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides 18-bit data storage capability through dual 9-bit functional blocks
• Features tri-state outputs for efficient bus interfacing
• Supports non-inverting logic operation

Applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches project requirements. Check obsolescence status as this part may be discontinued. Ensure environmental compliance documentation aligns with regulatory standards. Validate package integrity upon receipt to prevent handling damage.

Selection Notes

Select this component when an 18-bit register solution is required with FCT logic speed characteristics. Consider the TSSOP-56 footprint constraints during PCB layout. Evaluate power consumption against system thermal limits. Compare propagation delays with other FCT series alternatives if timing margins are tight. Verify input/output voltage compatibility with driving and receiving logic families.

Part Context

This device belongs to the FCT (Fast CMOS Technology) logic family, designed for high-speed operations compatible with TTL inputs. It serves as a bridge between standard logic levels and high-performance bus architectures. The 18-bit configuration allows for compact implementation of wide data paths without multiple discrete components.
