CY74FCT244ATSOCT

Overview

The CY74FCT244ATSOCT is an octal buffer and line driver manufactured by Texas Instruments under the FCT logic series. It features eight non-inverting inputs and 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, with a maximum propagation delay of 4.1 ns at 5 V. It provides high-level output current of -32 mA and low-level output current of 64 mA, while maintaining a static current of 200 nA. The component supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides octal buffering with three-state output control for bus interfacing
• Features low static power consumption suitable for energy-efficient designs
• Supports high-speed signal transmission with specified propagation delay metrics

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented communications

Procurement Notes

Verify the manufacturer designation carefully, as official documentation lists Texas Instruments as the producer for this part number despite potential historical associations with Cypress Semiconductor Corp. Confirm the specific suffix 'ATSOCT' matches the required package type and temperature grade. Ensure compliance with RoHS directives if environmental regulations apply to your project requirements.

Selection Notes

Select this component when an octal buffer with three-state capability is required for high-speed digital systems. The FCT series offers a balance of speed and power efficiency compared to older bipolar technologies. Consider the SOIC-20 package constraints and the specific voltage requirements of the target circuit during integration planning.

Part Context

This device belongs to the FCT (Fast CMOS) logic family, designed to replace faster bipolar counterparts with lower power consumption. The CY74FCT244T series specifically addresses applications needing multiple buffered outputs with tri-state functionality. It serves as a standard solution for data bus management in computer and industrial control systems.

Replacement Considerations

Check for pin-compatible alternatives within the same FCT family or other manufacturers offering equivalent octal buffer specifications. Verify that any substitute maintains the same 3-state output behavior and voltage compatibility.
