100307DC

Overview

The Fairchild Semiconductor 100307DC is a monolithic quint exclusive-OR/NOR gate belonging to the 100K series. It features five independent two-input logic functions with outputs configured for wire-OR capability. The device operates within an ECL voltage range of -4.2V to -5.7V and includes internal 50 kΩ pull-down resistors on all inputs. It provides 2000V ESD protection and supports industrial grade temperature ranges in specific packages.

Feature Summary

• Monolithic integration of five exclusive-OR/NOR logic gates
• Wire-OR output configuration for combined signal processing
• Internal 50 kΩ pull-down resistors on all input terminals
• High electrostatic discharge protection rating

Applications

• High-speed digital logic circuits requiring XOR/XNOR functionality
• Parity generation and checking systems
• Data comparison and error detection modules
• ECL-based computing architectures

Procurement Notes

Verify the package type against the datasheet, as the 'DC' suffix typically indicates a ceramic DIP variant while other suffixes may denote plastic or lead-free options. Confirm RoHS compliance status, as older 100K series parts often contain lead. Ensure the supplier provides the official Fairchild data sheet to validate the specific pinout and electrical characteristics for the exact manufacturing lot.

Selection Notes

Select this component when designing high-speed logic systems utilizing ECL technology that require multiple XOR/XNOR operations in a single footprint. The integrated pull-down resistors simplify biasing requirements. Consider the 100K series performance metrics regarding propagation delay and power dissipation relative to system constraints before finalizing the design.

Part Context

This part belongs to the Fairchild 100K series, a family of low-power ECL logic devices. The 100307 specifically implements quint exclusive-OR/NOR functions. It is functionally compatible with similar industry-standard ECL gates, allowing for direct replacement in legacy designs without circuit modification.

Replacement Considerations

The 100107 is a pin and function compatible alternative within the same series. Verify that the substitute device matches the required operating temperature range and package dimensions for the target application.
