CY74FCT2244ATSOC

Overview

The CY74FCT2244ATSOC is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features non-inverting polarity with three-state outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters 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 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 eight-channel buffering with tri-state output capability for signal isolation and driving.

Applications

• Signal buffering in digital systems
• Line driving applications requiring high fan-out

Procurement Notes

Verify the specific suffix 'A' against official datasheets to confirm performance grade or speed bin variations. Ensure the SOIC-20 package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5V CMOS/TTL interfaces. Consider the propagation delay and drive strength relative to load capacitance. Verify that the operating temperature range meets the environmental requirements of the intended application design.

Part Context

This part belongs to the Texas Instruments CY74FCT2244T family of octal buffers. It shares functional similarities with other FCT series devices but is distinguished by its specific pinout, package type, and electrical characteristics defined for the 20-SOIC configuration.

Replacement Considerations

Consult official substitution guides for compatible parts. Generic equivalents may differ in propagation delay or drive current. Verify pin compatibility and electrical specifications before replacing.
