CY74FCT16240ATPVC

Overview

The CY74FCT16240ATPVC is a CMOS bus driver from the FCT logic series, manufactured by Texas Instruments. It features four independent drivers, each configured for 4-bit data transmission with inverted output polarity. The device utilizes a 48-pin SSOP package and operates within a supply voltage range of 4.5V to 5.5V. It provides three-state outputs capable of sourcing 32mA and sinking 64mA. The component supports surface-mount installation and functions reliably 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 high-drive three-state outputs suitable for direct interface with CMOS and TTL loads
• Operates on a single 5V power supply with defined low-level and high-level current capabilities

Applications

• High-speed data bus buffering in computer systems
• Clock distribution networks requiring signal inversion
• Memory address and data line drivers in embedded controllers

Procurement Notes

Verify the specific suffix 'ATPVC' against the manufacturer's latest datasheet to confirm pinout compatibility and electrical characteristics. Ensure the procurement channel provides valid traceability documentation. Confirm that the package dimensions match the design footprint requirements before finalizing orders.

Selection Notes

Select this component when designing circuits requiring inverted 4-bit bus driving with high current capacity. It is appropriate for applications needing robust signal integrity at standard 5V logic levels. Consider the 48-SSOP package constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability.
