CY74FCT2244TSOCTG4

Overview

The CY74FCT2244TSOCTG4 is an octal buffer and line driver from the Texas Instruments FCT logic series. It features non-inverting logic with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical specifications include a high-level output current of -15 mA and a low-level output current of 12 mA. Propagation delay is specified at 6.5 ns when operating at 5 V. The component supports surface-mount installation and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides octal buffering capabilities with non-inverting signal transmission for digital data lines.
• Integrates three-state output control to facilitate bus-oriented architectures and system isolation.
• Utilizes CMOS technology to achieve low static power consumption while maintaining high-speed performance.

Applications

• Clock distribution networks requiring signal buffering and timing integrity.
• Bus-oriented systems utilizing bidirectional or unidirectional data transfer protocols.
• Memory mapping interfaces where high drive capability and controlled impedance are required.

Procurement Notes

Verify that the suffix 'G4' confirms compliance with RoHS3 directives and lead-free manufacturing standards as specified by Texas Instruments. Ensure the ordering part number matches the specific tape-and-reel packaging configuration intended for automated assembly processes. Cross-reference the manufacturer's latest datasheet to confirm active status and any potential pin-to-pin compatible alternatives within the FCT family.

Selection Notes

Select this component when designing systems that require eight-channel buffering with precise timing characteristics defined by the FCT series. The choice depends on the necessity for three-state outputs to manage bus contention effectively. Consider the 20-SOIC package dimensions for PCB layout constraints and verify that the 5V nominal supply aligns with the target system's power delivery infrastructure.

Part Context

This device belongs to the broader CY74FCT2244T product family, which includes variants such as the TSOC and TQCT packages. While the core logical function remains consistent across the family, physical attributes like moisture sensitivity levels and reel quantities differ based on the specific suffix. The G4 designation specifically indicates environmental compliance updates applied to the standard industrial-grade buffer.

Replacement Considerations

Publicly confirmed substitute part numbers include CY74FCT2244TSOC and CY74FCT2244TSOCG4. These alternatives share identical logical functionality and pinout configurations, allowing for direct integration into existing designs without schematic modifications.
