100363QC

Overview

The Fairchild Semiconductor 100363QC is a dual 8-to-1 multiplexer belonging to the 100K series. It features two independent circuits within a single package, providing signal routing capabilities for digital logic applications. The device operates with a supply voltage range of -4.2V to 5.7V and supports an operating temperature range of 0°C to 85°C. It is housed in a 28-pin PLCC package measuring 11.51x11.51 mm.

Feature Summary

• Dual independent 8:1 multiplexing channels
• Compatible with standard TTL logic families
• Wide single-supply voltage operation

Applications

• Digital signal routing systems
• Data acquisition multiplexing
• Logic circuit switching

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor's logic division was acquired by onsemi. Confirm the specific suffix 'QC' matches the required commercial grade specifications. Ensure the 28-PLCC package dimensions align with your PCB footprint requirements before ordering.

Selection Notes

Select this component when dual-channel 8-to-1 multiplexing is required in a compact surface-mount package. It is suitable for designs needing wide voltage tolerance and standard TTL compatibility. Verify that the 0°C to 85°C commercial temperature range meets your environmental constraints.

Part Context

This part belongs to the 100K series of logic components, which are widely used for general-purpose digital switching. The 100363QC specifically addresses applications requiring multiple signal paths to be managed efficiently within a limited board space using a standard PLCC form factor.

Replacement Considerations

Check for equivalents from onsemi, which succeeded Fairchild's logic business. Verify pinout compatibility and electrical characteristics against other 28-pin PLCC dual 8:1 multiplexers if sourcing from alternative manufacturers.
