CY74FCT2244CTQC

Overview

The CY74FCT2244CTQCT is an octal buffer and line driver from the FCT logic series, manufactured by Texas Instruments. It features eight non-inverting inputs driving three-state outputs 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 high-level output current of -15 mA and a low-level output current of 12 mA. Propagation delay is specified at 4.1 ns at 5 V. The component supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Provides buffering and line driving capabilities for digital signals
• Features tri-state outputs for bus-oriented memory and circuit applications
• Supports CMOS input levels with TTL-compatible output drive

Applications

• Bus-oriented memory systems
• Clock drivers
• Buffering and line driving applications

Procurement Notes

Verify the specific suffix 'CTQC' against official Texas Instruments documentation, as standard listings often reference 'CTQCT'. Confirm package type accuracy, as datasheets typically specify QSOP-20 for this family variant. Ensure RoHS compliance status matches current manufacturing revisions. Cross-reference ordering part numbers with authorized distributors to avoid discrepancies in suffix codes that may indicate different packaging or material compositions.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5V CMOS logic interfaces. The FCT series offers faster switching speeds compared to standard LS logic while maintaining CMOS power consumption characteristics. Consider the 20-pin QSOP footprint for PCB layout constraints. Verify input compatibility with source devices to ensure proper logic level translation between CMOS sources and TTL loads.

Part Context

This device belongs to the CY74FCT2244T family of octal buffers. It serves as a non-inverting buffer solution for high-speed digital designs. The FCT technology combines the speed of bipolar circuits with the low power of CMOS. Similar parts in the series include the CY74FCT244, which shares the octal configuration but may differ in specific drive strengths or package options.
