CY74FCT244CTSOC

Overview

The CY74FCT244CTSOC is an octal buffer and line driver with three-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and utilizes CMOS technology. The device operates within a supply voltage range of 4.75 V to 5.25 V. It features eight input lines and provides non-inverting signal buffering. Key electrical parameters include a high-level output current of -32 mA, a low-level output current of 64 mA, and a static current of 200 nA. The propagation delay is specified as 4.1 ns at 5 V. The component is housed in a 20-pin SOIC package designed for surface mount installation.

Feature Summary

• Provides octal buffering and line driving capabilities with three-state output control
• Supports non-inverting signal transmission using FCT CMOS logic architecture
• Delivers high drive strength suitable for bus-oriented applications

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiplexer and demultiplexer decoder inputs

Procurement Notes

Verify the specific suffix 'CSOC' against the official Texas Instruments datasheet to confirm package dimensions and thermal characteristics. Ensure the ordering part number matches the required RoHS compliance status and moisture sensitivity level. Cross-reference the manufacturer date code and assembly location if environmental certifications are critical for the final product integration.

Selection Notes

Select this component when an octal buffer with three-state outputs is required for 5 V systems. The FCT series offers faster switching speeds compared to standard TTL equivalents. Consider the 20-SOIC package size for PCB layout constraints. Verify that the load capacitance requirements do not exceed the device's specified limits to maintain signal integrity at the target operating frequency.

Part Context

This device is part of the CY74FCT244T family, which includes various packaging options such as TSSOP and QSOP. The CY74FCT244CTSOC specifically denotes the SOIC-20 variant. It serves as a direct replacement for legacy 74FCT244 devices in designs requiring improved speed and lower power consumption while maintaining compatible pinouts and logical functions.

Replacement Considerations

The CY74FCT244CTQCT is a documented alternative offering the same functional specifications in a different package format.
