100319QC

Overview

The Fairchild Semiconductor 100319QC is a non-inverting buffer integrated circuit designed for high-speed digital signal processing applications. It features six independent buffer elements, each capable of handling 6-bit data paths with complementary outputs to support differential signaling requirements. The device operates within a supply voltage range extending up to -5.7V, making it suitable for specific negative voltage logic families or specialized interface circuits. It is housed in a 28-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads, providing robust mechanical stability and thermal performance for industrial and commercial environments.

Feature Summary

• Provides six independent non-inverting buffer channels for signal conditioning
• Features complementary output configurations to support differential transmission lines
• Designed for operation with negative supply voltages up to -5.7V
• Utilizes a 28-lead PLCC package for reliable surface mounting

Applications

• High-speed digital bus buffering in communication systems
• Signal translation between different logic families requiring complementary outputs
• Differential line driving in data acquisition equipment
• Clock distribution networks in complex digital architectures

Procurement Notes

Verify the exact suffix codes against official Fairchild documentation to ensure correct voltage ratings and temperature grades. Confirm package integrity upon receipt, as PLCC leads are susceptible to bending during shipping. Cross-reference the manufacturer part number with current distributor catalogs to avoid obsolete stock. Ensure compliance with RoHS directives if required by your manufacturing standards. Request detailed datasheets from authorized suppliers to validate electrical characteristics before integration.

Selection Notes

Select this component when designing circuits that require non-inverting buffering with complementary outputs for differential signaling. Consider the -5.7V operating limit to ensure compatibility with your power supply rails. The 28-PLCC package dictates specific PCB footprint requirements; verify land pattern dimensions during layout. Evaluate propagation delay specifications from the official datasheet to meet timing constraints. Compare pinout configurations with existing designs to prevent soldering errors during assembly.

Part Context

Fairchild Semiconductor specializes in power management and discrete semiconductors. The 100319QC belongs to their logic buffer family, addressing needs for signal integrity in high-speed digital interfaces. This component supports system reliability through robust packaging and defined electrical parameters.
