The 100319QI is a non-inverting buffer from Fairchild Semiconductor, part of the 100K ECL logic family. It operates from -4.2V to -5.7V, with a high output drive capability of 100mA. The device features complementary outputs and a single channel, making it suitable for high-speed ECL signal buffering. Housed in a 28-pin LCC (J-Lead) package, it is designed for legacy high-performance systems. Typical applications include clock distribution, backplane driving, and test equipment in ECL-based environments.
- High 100mA Drive: Provides strong signal levels for long-distance transmission.
- Complementary Outputs: Supports differential signaling for noise immunity.
- ECL Compatibility: Interfaces directly with legacy 100K ECL logic.
- Wide Temperature Range: Operates from -40°C to 85°C for industrial use.
- Compact LCC Package: Suitable for space-constrained high-speed designs.
High-Speed Clock Distribution
Use the 100319QI to buffer and distribute ECL clock signals in supercomputer and mainframe systems. The complementary outputs provide both clock phases for differential signaling.
Telecommunications Backplanes
Drive high-frequency signals across long backplane traces in legacy telecom equipment. The 100mA output current ensures strong signal propagation.
Test and Measurement Instruments
