CY74FCT16244ATPACT

Overview

The CY74FCT16244ATPACT is a 16-bit buffer and line driver manufactured by Texas Instruments under the FCT logic series. It features non-inverting outputs with three-state control, housed in a 48-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an industrial temperature range from -40°C to +85°C. Key electrical parameters include a propagation delay of 4.8 ns at 5 V, a low-level output current of 64 mA, and a high-level output current of -32 mA. Power dissipation is rated at 1 W.

Feature Summary

• Provides 16-bit buffering for high-speed bus interfaces
• Includes Ioff circuitry to prevent backflow during partial power-down
• Features edge-rate control circuits to improve noise characteristics

Applications

• Memory bus driving applications
• Clock signal distribution
• High-speed and low-power bus interface systems

Procurement Notes

Verify component authenticity as this part may be obsolete or discontinued. Confirm package integrity and pin alignment against the TSSOP-48 specification. Ensure the manufacturer designation matches official records, noting potential transitions between Cypress Semiconductor and Texas Instruments. Validate RoHS compliance status through current datasheets before integration into production designs.

Selection Notes

Select this component for designs requiring 16-bit non-inverting buffering with three-state capability. It is suitable for driving high capacitance loads and low impedance backplanes. Consider the balanced output drive options if minimizing ground bounce is critical. Verify that the 4.5 V to 5.5 V operating voltage aligns with the system power rails.
