100363FM-MLS

Overview

The National Semiconductor 100363FM-MLS is a dual data selector and multiplexer integrated circuit. It features two independent 8-to-1 multiplexing channels, providing a total of sixteen input lines selectable by three address bits per channel. The device operates within a supply voltage range of 4.2V to 5.7V, compatible with standard 5V logic systems. It is housed in a 24-pin CFlatPack package, designed for surface-mount applications requiring high isolation and fast switching speeds suitable for digital signal processing.

Feature Summary

• Dual independent 8:1 multiplexing architecture
• High isolation between input channels
• Fast switching capability for digital signal processing
• Compatible with standard 5V logic levels

Applications

• Digital signal processing systems
• Control applications requiring signal routing
• Data selection circuits in embedded systems

Procurement Notes

Verify the manufacturer origin as National Semiconductor, now part of Texas Instruments, due to corporate acquisitions. Confirm the specific suffix MLS indicates the CFlatPack package type. Check for obsolescence status or lifecycle notices from official distributors, as legacy analog components may have limited availability or require alternative sourcing strategies.

Selection Notes

Select this component when dual isolated 8:1 multiplexing is required in a compact surface-mount form factor. Ensure the system operates within the 4.2V to 5.7V supply range. Consider the 24-pin CFlatPack footprint for PCB layout compatibility. Verify that the switching speed meets the timing requirements of the target digital signal processing application.

Part Context

This component belongs to the family of analog signal switches and multiplexers produced by National Semiconductor. These devices are typically used for routing multiple input signals to a single output line based on control inputs. The 100363 series represents a dual-channel variant, offering greater integration density compared to single-channel counterparts in similar packages.

Replacement Considerations

Consult official Texas Instruments documentation for direct pin-compatible replacements or functional equivalents. Verify electrical parameters such as on-resistance and leakage current against potential substitute parts to ensure system performance remains unaffected.
