The 100352QC is a high-speed, non-inverting buffer from Fairchild Semiconductor's 100K ECL logic family. It provides one channel of signal buffering, operating from a negative supply of -4.2V to -5.7V. With a 100mA source current capability, it is designed for demanding high-frequency applications. Housed in a 28-LCC (J-Lead) package, this IC is suitable for telecommunications, RF test equipment, and aerospace systems where speed and signal integrity are critical.
- Ultra-High Speed (100K ECL): Propagation delays in the sub-nanosecond range, ideal for GHz signals.
- High Source Current (100mA): Drives low-impedance transmission lines effectively.
- Negative Supply Operation: Compatible with standard ECL power rails (-5.2V).
- Ceramic 28-LCC Package: Provides excellent thermal performance and high-frequency characteristics.
High-Frequency Clock Distribution
In telecommunications and data centers, the 100352QC buffers high-speed clock signals. ECL's differential outputs (if used) provide excellent noise immunity for GHz-range signals.
Supercomputer Interconnects
For legacy supercomputers and mainframes, this buffer drives long transmission lines with minimal skew. The 100mA source current handles characteristic impedance of 50-ohm lines.
RF Test Equipment
In RF signal generators, this ECL buffer maintains signal integrity at frequencies above 1GHz. The 28-LCC package minimizes parasitic inductance.
Aerospace and Defense Systems
For military-grade avionics, ECL logic provides the speed needed for radar signal processing. The 0°C to 85°C case temperature range suits harsh environments.
High-Speed Data Acquisition
In oscilloscopes and digitizers, this buffer conditions fast analog-to-digital converter clocks. Its negative supply operation is compatible with ECL-based ADC front-ends.
