CY74FCT2244TQCT

Overview

The CY74FCT2244TQCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs driving three-state outputs in a QSOP-20 surface-mount 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 6.5 ns at 5 V, a high-level output current of -15 mA, and a low-level output current of 12 mA. It draws a maximum operating supply current of 200 nA and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides eight-channel buffering with independent three-state control for bus-oriented architectures
• Delivers high-speed signal transmission with specified propagation delay characteristics
• Compatible with TTL input levels while utilizing CMOS technology for low power consumption

Applications

• Clock buffering and distribution systems
• Memory module address and data line drivers
• High-performance computing bus interfaces

Procurement Notes

Verify the specific suffix TQC against official datasheets to confirm the QSOP-20 package type and reel packaging configuration. Ensure compatibility with moisture sensitivity level requirements during storage and handling. Confirm that the ordering part number matches the exact electrical specifications required for the target application design.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state capability and TTL-compatible inputs. It is suitable for applications demanding moderate drive strength and low static power consumption. Consider the thermal performance and package constraints of the QSOP-20 form factor during PCB layout planning.

Part Context

This component is part of the broader CY74FCT2244T family from Texas Instruments, which includes variants such as CY74FCT2244TSOC and CY74FCT2244CTSOC. These devices share similar functional characteristics but differ in package types like SOIC or SOP. The family serves as a standard solution for digital signal buffering in industrial and commercial electronics.
