The 100313QI from Fairchild Semiconductor is a high-speed ECL buffer designed for demanding signal distribution and conditioning tasks. This single-channel device offers both inverting and non-inverting outputs, providing design flexibility. With a wide negative supply voltage range of -4.2V to -5.7V and a robust 50mA output current capability, it can drive terminated transmission lines and high-capacitance loads effectively. Housed in a 28-pin LCC package, it is suitable for space-constrained applications requiring reliable performance.
- High Output Current (50mA): Drives low-impedance and terminated lines, ensuring signal integrity over long distances.
- Dual Output Polarity: Provides both inverting and non-inverting signals, reducing component count and simplifying design.
- Wide Temperature Range (-40°C to 85°C): Ensures reliable operation in industrial and automotive environments.
- Standard ECL Supply Voltage: Operates from -4.2V to -5.7V, compatible with existing ECL systems.
High-Speed Data Distribution
Use the 100313QI to buffer and distribute high-frequency clock or data signals across multiple loads. Its 50mA output current can drive low-impedance, terminated transmission lines, minimizing signal reflections and maintaining signal integrity.
ECL-to-ECL Interfacing
In systems using ECL logic, this buffer provides both inverting and non-inverting outputs, allowing flexible signal polarity control without additional components. This simplifies board layout and reduces propagation delays.
