CY74FCT16240ATPVCT

Overview

The CY74FCT16240ATPVCT is a CMOS bus driver from the FCT logic series, manufactured by Texas Instruments. It features four independent 4-bit drivers with inverted outputs and 3-state capability. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 48-SSOP package. It provides high drive currents of 32mA for high-level output and 64mA for low-level output, ensuring robust signal integrity across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent 4-bit bidirectional bus drivers with inverted logic functionality
• Features 3-state outputs allowing multiple drivers to share a common data bus
• Utilizes advanced CMOS technology for low power consumption and high-speed operation

Applications

• High-density memory buffer applications
• Clock distribution circuits
• Bus-oriented architectures requiring signal inversion and isolation

Procurement Notes

Verify the specific suffix 'CT' indicates tape and reel packaging configuration when sourcing. Confirm the manufacturer designation as Texas Instruments, noting that Cypress was the original developer before acquisition. Ensure compatibility with standard 48-SSOP footprints during PCB layout verification.

Selection Notes

Select this component for designs requiring 16-bit wide data paths with active-low output polarity. Compare against non-inverting variants like the 74FCT16244 if signal phase alignment differs. Consider the 48-SSOP package constraints regarding thermal dissipation and pin pitch requirements for automated assembly processes.

Part Context

This part belongs to the 74FCT family, representing Fast CMOS technology that bridges TTL and CMOS performance. It serves as a successor to older 74F series devices, offering improved switching speeds while maintaining compatible logic levels. The 16240 variant specifically addresses 16-bit bus driving needs within compact surface-mount form factors.

Replacement Considerations

Direct equivalents include IDT74FCT16240ATPA or IDT74FCT16240ATPF. Cross-reference with Texas Instruments' own 74FCT16240ATPVCR for reel versus tube packaging differences. Verify pinout compatibility before substituting with generic FCT-series alternatives.
