100316QC

Overview

The Fairchild Semiconductor 100316QC is a monolithic quad driver belonging to the 100K series, designed for ECL logic applications. It features five functions with two inputs per function and provides true outputs in a 28-pin plastic leaded chip carrier (LCC-28) package. The device operates within a voltage compensated range of -4.2V to -5.7V and includes open-emitter output characteristics. It offers 2000V ESD protection and incorporates 50 kΩ pull-down resistors on all inputs. The component supports an operating temperature range from -55°C to 85°C and is housed in a square plastic epoxy package measuring approximately 11.43 mm in length.

Feature Summary

• Monolithic quad driver architecture with common enable functionality
• Voltage compensated operation suitable for standard ECL power supplies
• Integrated 50 kΩ input pull-down resistors to minimize loading
• High electrostatic discharge protection rating of 2000V

Applications

• ECL line driving and buffering
• Digital signal processing interconnects
• High-speed data transmission systems

Procurement Notes

Verify the specific suffix 'QC' against the manufacturer's current catalog to confirm availability and exact pinout configuration. Ensure the procurement documentation specifies the LCC-28 plastic package variant. Cross-reference the part number with official Fairchild or on Semiconductor databases to validate compliance with RoHS standards and environmental certifications before finalizing orders.

Selection Notes

Select this component when a low-power quad driver compatible with existing 100113 or 100112 designs is required. The 100316QC provides significant power reduction compared to earlier generations while maintaining pin and function compatibility. Consider the open-emitter output structure for wired-OR applications and verify that the -55°C to 85°C temperature range meets the operational requirements of the target environment.

Part Context

The 100316QC is part of the broader 100K series of high-speed ECL logic devices manufactured by Fairchild Semiconductor. This series is characterized by its voltage-compensated design, which simplifies power supply requirements for ECL circuits. The device serves as a specialized driver within the family, offering integrated logic functions in a compact surface-mount package suitable for dense PCB layouts.

Replacement Considerations

The 100316QC is pin and function compatible with the 100113 and 100112 models. Designers may substitute these parts if system performance allows for the specific electrical differences between the 100K and 1001 series. Verify that the replacement maintains the required ESD protection levels and output drive capabilities.
