CY74FCT163244APVC

Overview

The CY74FCT163244APVC 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 outputs with three-state capability, housed in a 48-pin SSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 4.2 ns at 5 V, low-level output current of 32 mA, and high-level output current of -32 mA. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering and line driving capabilities for digital signal integrity.
• Features three-state outputs to facilitate bus-oriented architectures.
• Utilizes FCT CMOS technology for high-speed performance.

Applications

• Bus-oriented system architectures requiring signal buffering
• Clock distribution networks
• Memory interface drivers

Procurement Notes

Verify the specific suffix APVC against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement source provides valid RoHS status documentation, as legacy FCT parts may have varying compliance levels. Confirm moisture sensitivity level (MSL) ratings prior to surface mount assembly to prevent damage during reflow soldering processes.

Selection Notes

Select this component when designing systems requiring 16-bit wide data paths with high drive strength. The FCT series offers speed comparable to LS-TTL but with CMOS power consumption. Consider the 48-SSOP package constraints for PCB layout. Verify that the application environment stays within the specified -40°C to +85°C temperature range for reliable operation.

Part Context

This part is part of the broader 74FCT family of high-speed CMOS logic devices. It serves as a buffer variant within the FCT product line, distinct from transceivers or latches. The device is designed for applications needing fast switching speeds and strong output currents, typical in industrial and commercial computing environments where signal integrity over longer traces is critical.

Replacement Considerations

Direct replacements include other 16-bit FCT buffers such as the CY74FCT163244ATPVC or CY74FCT163244CPVC, provided the package type matches. Cross-referencing with the base 74FCT163244 specification is necessary to ensure functional equivalence regarding pinouts and electrical characteristics.
