CY74FCT2244ATQC

Overview

The CY74FCT2244ATQC is an octal buffer and line driver from the FCT logic series, manufactured by Texas Instruments. It features eight non-inverting inputs with three-state outputs, housed in a 20-pin QSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.6 ns at 5 V, high-level output current of -15 mA, and low-level output current of 12 mA. Static current is specified at 100 nA, with a maximum operating temperature of +85°C.

Feature Summary

• Provides eight non-inverting buffered channels for signal transmission
• Features three-state outputs to facilitate bus-oriented architectures
• Incorporates CMOS technology for low static power consumption

Applications

• Bus drivers for data transmission systems
• Memory address and data drivers
• System clock distribution buffers

Procurement Notes

Verify the manufacturer designation carefully, as the part number is primarily associated with Texas Instruments despite the query specifying Cypress Semiconductor Corp. Confirm the specific suffix 'ATQC' corresponds to the QSOP-20 package and industrial temperature grade. Ensure compatibility with the required 5V logic family standards before integration into the design.

Selection Notes

Select this component when an octal buffer with high-speed performance and low power dissipation is required. The FCT series offers speed comparable to LS TTL but with CMOS input characteristics. Consider the 20-pin QSOP package constraints and ensure the application supports the 4.75V to 5.25V operating voltage range for optimal timing specifications.

Part Context

This component belongs to the 74FCT2244T family of octal buffers. It serves as a high-speed interface solution for digital systems requiring signal isolation or drive capability enhancement. The FCT (Fast CMOS Technology) series bridges the performance gap between standard CMOS and bipolar TTL logic families.
