100363QI

Overview

The Fairchild Semiconductor 100363QI is a dual 8-input multiplexer belonging to the 100K series. It functions as a 2x8:1 signal selector, allowing independent routing of two sets of eight input signals to corresponding outputs via Data Select inputs. The device is housed in a 28-LCC (J-Lead) surface-mount package, suitable for logic signal switching applications requiring compact integration and reliable data selection.

Feature Summary

• Dual independent 8-to-1 multiplexing channels
• Logic signal routing and selection capability
• Surface-mount LCC package design

Applications

• Logic signal routing systems
• Data selection circuits
• Multiplexer-based signal processing

Procurement Notes

Verify the specific package variant, as datasheets may list 28-LCC or 28-PLCC. Confirm manufacturer lineage due to corporate acquisitions. Ensure compatibility with existing board layouts for J-Lead components. Check for updated documentation from the current rights holder.

Selection Notes

Select this component for applications requiring dual-channel 8-input signal selection. The 100K series indicates specific logic family characteristics. Verify pinout compatibility with alternative packages like CDIP if redesigning. Ensure voltage levels match system requirements.

Part Context

This part belongs to the 100K series of logic multiplexers manufactured by Fairchild Semiconductor. It serves as a digital signal switch, distinct from analog switches. The QI suffix typically denotes a specific package and temperature grade variation within the broader 100363 product line.

Replacement Considerations

Public confirmed substitutes include 100363DC and 100363QC. These variants offer different packaging options such as CDIP while maintaining the same 2x8:1 multiplexing functionality. Verify pin compatibility before substitution.
