CY74FCT16244CTPACT

Overview

The CY74FCT16244CTPACT is a 16-bit buffer and line driver manufactured by Texas Instruments. It belongs to the FCT logic series and features non-inverting, three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes a 48-pin TSSOP surface-mount package. Key electrical parameters include a propagation delay of 4.1 ns at 5 V, a maximum low-level output current of 64 mA, and a maximum high-level output current of -32 mA. The component supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering with three-state control for bus interface applications
• Features balanced output drivers to reduce system switching noise and ground bounce
• Supports partial power-down mode via Ioff circuitry to prevent backflow currents

Applications

• Memory bus driving
• Clock signal distribution
• High-speed and low-power bus interfaces

Procurement Notes

Verify the specific suffix 'PACT' against official Texas Instruments documentation to confirm the exact tape-and-reel quantity and packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the 48-pin TSSOP footprint matches your PCB design constraints. Validate the lead time and availability status directly with authorized distributors as inventory levels fluctuate.

Selection Notes

Select this component when a 16-channel buffer with three-state capability is required for 5V CMOS logic systems. It is suitable for designs needing reduced ground bounce and controlled edge rates. Consider the TSSOP-48 package size relative to available board space. Compare performance metrics such as propagation delay and output drive strength against alternative FCT series devices if tighter timing or higher current specifications are necessary.

Part Context

This part is part of the CY74FCT16244T family of 16-bit buffers and line drivers. The family includes variants with different speed grades and packaging options, such as the AT and CT speed bins. These devices are designed for high-density applications requiring small form factors like SSOP and TSSOP packages. The FCT technology combines CMOS density with Schottky TTL speed characteristics.

Replacement Considerations

Check for direct pin-compatible alternatives within the same FCT family, such as other CY74FCT16244 variants with different suffixes. Verify that any substitute maintains the 4.5V to 5.5V operating voltage and 16-bit width. Ensure the replacement offers equivalent three-state output functionality and similar propagation delay characteristics.
