CY74FCT16244ATPACT

Overview

The CY74FCT16244ATPACT is a 16-bit buffer and line driver manufactured by Texas Instruments. It belongs to the FCT logic series and utilizes CMOS technology. The device features non-inverting polarity with 3-state outputs, housed in a 48-pin TSSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a propagation delay of 4.8 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. The component supports surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering and driving capabilities for digital signal lines.
• Features 3-state outputs allowing for bus-oriented architectures.
• Utilizes FCT CMOS technology for high-speed performance.

Applications

• Bus-oriented systems requiring signal buffering
• Memory address drivers
• Clock distribution circuits

Procurement Notes

Verify component authenticity through authorized channels due to potential availability issues. Confirm package integrity upon receipt as the TSSOP-48 form factor requires careful handling. Check manufacturing date codes against project requirements. Ensure compliance with RoHS directives if applicable to the specific revision. Validate pinout compatibility during integration planning.

Selection Notes

Select this component when 16-channel non-inverting buffering is required with 3-state control. Compare against similar FCT series devices based on package constraints and drive strength needs. Consider the 4.5 V to 5.5 V operating range for system power design. Evaluate thermal dissipation requirements given the 1 W power dissipation rating.

Part Context

This part is part of the 74FCT16244 family of high-speed CMOS logic buffers. It serves as a parallel interface solution for connecting microprocessors to peripheral devices or memory modules. The device replaces older bipolar technologies with faster switching speeds and lower power consumption typical of the FCT series.

Replacement Considerations

Check for direct substitutes such as the CY74FCT16244ATPVCT, noting that some variants may be discontinued. Verify pin-to-pin compatibility before substitution. Review datasheet revisions for any functional changes in alternative packages.
