74F244SC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74F244SC is an octal buffer and line driver featuring three-state outputs, belonging to the F/FAST logic series. It operates on a single 5 V supply voltage and utilizes TTL technology within a 20-pin small outline package (SOP). The device comprises two independent four-bit buffers with separate output enable inputs, providing non-inverting data transmission from A inputs to Y outputs when enabled.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides high-speed operation characteristic of the F/FAST series for efficient signal buffering
• Features three-state outputs that isolate the bus when disabled to prevent contention
• Organized as two independent four-bit sections allowing flexible bidirectional or unidirectional configurations

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers in computer systems
• Clock drivers for timing distribution networks
• Bus-oriented receivers for data communication interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix SC against the manufacturer datasheet to confirm the exact package variant and temperature rating. Ensure compatibility with existing board layouts regarding pin pitch and footprint dimensions. Confirm lead times and availability directly with authorized distributors as stock levels fluctuate.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when fast switching speeds are required alongside low power dissipation compared to standard Schottky TTL. It serves as a functional replacement for slower logic families while maintaining pin compatibility. Consider the 5 V operating requirement and ensure input voltages remain within specified limits for reliable performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74F family of advanced high-speed logic devices manufactured by Fairchild Semiconductor. It shares architectural similarities with other octal bus drivers but offers superior speed characteristics. The SOP-20 packaging allows for surface-mount assembly in compact electronic designs requiring robust signal integrity.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the NXP 74F244 and Texas Instruments SN74F244. These alternatives maintain identical logical functionality and pinout configurations. Verify package dimensions and thermal characteristics before implementing any cross-manufacturer replacements.
