CY74FCT2244TSOCT

Overview

The CY74FCT2244TSOCT is an octal buffer and line driver from the Texas Instruments FCT logic series. It features eight non-inverting inputs and 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 6.5 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 octal buffering with tri-state output capability for bus-oriented systems
• Utilizes Fast CMOS technology for high-speed signal transmission
• Features TTL-compatible input thresholds for direct interface with TTL logic

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• High-performance register files

Procurement Notes

Verify the specific suffix 'TQC' indicates the QSOP-20 tape and reel packaging configuration distinct from tube-packed variants. Confirm moisture sensitivity level requirements for surface mount assembly processes. Ensure the ordering part number matches the exact package style and reflow soldering profile needed for the target application board design.

Selection Notes

Select this component when an octal buffer with tri-state control is required in a compact QSOP footprint. Compare against SOIC-20 versions if reel packaging is not mandatory. Consider the 6.5 ns propagation delay and drive strength relative to system timing constraints. Verify compatibility with existing 5V logic families and thermal management needs for the chosen enclosure type.

Part Context

This part belongs to the CY74FCT2244T family of octal buffers. It shares functional characteristics with other FCT series devices but differs in physical packaging. The TSOC designation specifically identifies the thin shrink small-outline package variant. It serves as a digital interface component within broader logic IC portfolios designed for high-speed data transfer applications.

Replacement Considerations

CY74FCT2244TSOC (SOIC-20 tube) offers identical electrical performance in a different package format.
