74FCT2244ATSOCTE4

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74FCT2244ATSOCTE4 is an octal buffer and line driver featuring non-inverting outputs with three-state capability. It operates within a supply voltage range of 4.75 V to 5.25 V, supporting high-speed signal transmission with propagation delays up to 8 ns at 5 V. The device provides 15 mA output source current and 12 mA sink current, ensuring robust drive capabilities for bus-oriented applications. Designed in a 20-pin SOIC package, it includes on-chip 25-Ω series resistors to minimize noise from reflections.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates on-chip 25-ohm output series resistors to reduce transmission-line reflection noise and improve signal integrity.
• Features edge-rate control circuitry designed to significantly enhance noise characteristics during switching operations.
• Supports partial-power-down mode operation through Ioff circuitry that disables outputs to prevent damaging backflow currents.
• Provides full compatibility with TTL input and output logic levels without requiring external interface components.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• System clock drivers
• Bus-oriented transmitters and receivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'E4' against the manufacturer's latest documentation to confirm environmental compliance status and lead finish specifications. Ensure the tape and reel packaging quantity matches the required production volume. Confirm the active status of this part number directly with Texas Instruments or authorized distributors before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with integrated termination resistors to simplify board layout. Consider the 8 ns maximum propagation delay for timing-critical paths operating at 5 V. Verify that the 20-pin SOIC package dimensions fit the available PCB footprint and that the thermal impedance characteristics are suitable for the intended operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the FCT logic family, which offers performance comparable to bipolar logic while maintaining CMOS power efficiency. The 74FCT2244 variant specifically provides non-inverting functionality, distinguishing it from inverting buffers like the 74FCT240. It serves as a high-drive solution for interfacing between different logic families or driving long traces on high-performance boards.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as the 74FCT2244TSOCTE4 if speed grade variations are acceptable. Verify pinout compatibility with other octal buffers in the FCT family, noting that some variants may lack the integrated series resistors or have different electrical characteristics.
