74F828SC

Overview

The Fairchild Semiconductor 74F828SC is a 10-bit buffer and line driver belonging to the F/FAST logic series. It features non-inverting outputs with 3-State capability, allowing for high-impedance states when disabled. The device operates within a standard voltage range and supports dual output enable controls activated by low signals. Packaged in a 24-pin SOIC format, it is designed for bus driving applications requiring fast switching speeds and reliable signal integrity in digital systems.

Feature Summary

• Provides 10-bit buffering with non-inverting logic functionality
• Features 3-State outputs controlled by dual low-active enable inputs
• Designed for high-speed bus driving applications using F/FAST technology

Applications

• Bus driver circuits in computer systems
• Signal buffering for high-speed data lines
• Line driving in communication interfaces

Procurement Notes

Verify the specific package variant and manufacturer revision against the original datasheet before procurement. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements. Confirm that the non-inverting configuration meets the system design specifications. Check for any updated environmental compliance certifications if required by the final product regulations.

Selection Notes

Select this component when a 10-bit wide bus interface with tri-state control is required. The F/FAST series offers faster propagation delays compared to standard TTL equivalents. Consider the SOIC package dimensions for surface mount assembly constraints. Verify that the input voltage levels are compatible with the driving logic family used in the circuit design.

Part Context

This part belongs to the widely adopted 74F logic family, known for improved speed over earlier 74LS variants. The 74F828 specifically addresses the need for multi-bit bus drivers with isolation capabilities. Its design supports complex digital architectures where multiple devices share common data lines without interference during inactive periods.
