CY74FCT16240ATPACT

Overview

The CY74FCT16240ATPACT is a CMOS bus driver manufactured by Texas Instruments, belonging to the FCT logic series. It features four independent drivers, each configured for 4-bit operation, providing a total of 16 input and 16 output lines. The device utilizes a non-inverting logic polarity with 3-state outputs controlled by an active-low enable signal. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 48-pin TSSOP package. The component is rated for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Provides high-speed data transmission via four independent 4-bit bus drivers
• Features 3-state outputs allowing direct connection to system buses
• Utilizes advanced CMOS technology for low power consumption

Applications

• High-performance memory mapping systems
• Clock drivers and buffer circuits
• Control line buffering in embedded systems

Procurement Notes

Verify the specific suffix 'TPACT' against the manufacturer's official datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like the CY74FCT16240ATPVCR or standard 74FCT equivalents. Confirm RoHS compliance status directly from the latest revision notes.

Selection Notes

Select this component when designing systems requiring 16-bit wide bus interfacing with minimal propagation delay. The FCT series offers speed comparable to LS-TTL but with CMOS power efficiency. Verify that the target application requires non-inverting logic and that the 48-pin TSSOP footprint matches the PCB layout constraints. Consider thermal dissipation requirements given the 1 W power dissipation rating.

Part Context

This device is part of the broader 74FCT family of high-speed CMOS logic devices produced by Texas Instruments. The FCT series is designed to bridge the performance gap between standard TTL and faster AC/ACT families. The CY74FCT prefix indicates Cypress Semiconductor origin prior to its acquisition by Infineon and subsequent integration into Texas Instruments' portfolio, reflecting the lineage of the original design.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT74FCT16240ATPA and 74FCT16240ATPF. These alternatives share identical logical functions and pin configurations but may differ in manufacturing process or packaging details. Always cross-reference electrical characteristics such as output current drive capabilities before substitution.
