100370QC

Overview

The Fairchild Semiconductor 100370QC is a monolithic quint exclusive-OR/NOR gate belonging to the 100K series. It features five independent 2-input XOR/XNOR functions with a wire-OR output configuration. The device operates within an ECL voltage compensated range of -4.2V to -5.7V and includes 50 kΩ pull-down resistors on all inputs. It provides 2000V ESD protection and is available in a 28-pin plastic quad flat pack (LCC) package.

Feature Summary

• Monolithic quint exclusive-OR/NOR gate architecture
• Wire-OR output capability for combined logic functions
• Integrated 50 kΩ input pull-down resistors
• High electrostatic discharge protection rating

Applications

• High-speed digital logic processing systems
• Parity generation and checking circuits
• Data comparison and error detection modules
• ECL-based computing architectures

Procurement Notes

Verify the specific suffix 'QC' against official Fairchild documentation to confirm package type, temperature grade, and material composition. Ensure compatibility with existing ECL power supply rails (-4.2V to -5.7V). Confirm pinout alignment with system board layouts, as variations exist within the 100K family. Validate RoHS status if required by assembly specifications.

Selection Notes

Select this component when a high-density solution for multiple XOR/XNOR operations is required in an ECL environment. The integrated pull-down resistors simplify input biasing. Consider the LCC package for space-constrained designs requiring surface-mount technology. Verify thermal management requirements for the plastic package variant.

Part Context

The 100370QC is part of Fairchild's 100K series, designed for low-power ECL applications. This series offers performance comparable to standard ECL logic while consuming less power. The quint configuration consolidates five logic gates into a single package, reducing board space and interconnect complexity compared to discrete solutions.

Replacement Considerations

The 100307QC is functionally compatible and pin-compatible with the 100370QC. Both devices serve as low-power quint exclusive-OR/NOR gates within the same logic family. Verify package availability and specific suffix designators before substitution.
