{"product_id":"100313qc","title":"100313QC","description":"\u003cp\u003eThe 100313QC is a high-speed ECL buffer from Fairchild Semiconductor, part of the 100K logic family. It provides both inverting and non-inverting outputs from a single input, enabling flexible signal distribution in differential or single-ended configurations. Operating from a negative supply of -4.2V to -5.7V, it is designed for very high-frequency applications with propagation delays typically under 1ns. The 28-LCC (J-Lead) package is suitable for surface-mount assembly. Typical applications include clock distribution, differential signaling, and high-speed test equipment.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUltra-High Speed: ECL technology provides propagation delays under 1ns, essential for GHz-range signals.\u003c\/li\u003e\n\u003cli\u003eComplementary Outputs: Provides both inverting and non-inverting signals, simplifying differential designs.\u003c\/li\u003e\n\u003cli\u003eHigh Output Current (50mA): Drives transmission lines or multiple ECL loads directly.\u003c\/li\u003e\n\u003cli\u003eNegative Supply Operation: Compatible with standard ECL power rails (-5.2V typical).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHigh-Speed Clock Distribution\u003c\/h3\u003e\u003cp\u003eIn telecommunications or test equipment, buffer ECL clock signals with rise times under 1ns.
