100118FC

Overview

The National Semiconductor 100118FC is a configurable logic gate belonging to the 100K series. It integrates one circuit capable of functioning as an AND/OR gate or OR-AND/-INVERT gate. The device features a total of 19 inputs, distributed as five, four, four, and two inputs per configuration segment. It is housed in a 24-CFlatpack package and is designed for general-purpose digital logic applications requiring flexible gate configurations within standard TTL-compatible voltage ranges.

Feature Summary

• Configurable multi-function logic capability supporting AND/OR and OR-AND/-INVERT operations
• High input count flexibility with 19 total inputs distributed across multiple segments
• Standard 100K series compatibility for integration into existing digital logic systems

Applications

• Digital logic circuit design requiring configurable gate functions
• System prototyping where variable logic configurations are necessary
• Industrial control logic interfaces utilizing standard TTL families

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor's logic assets were acquired by Texas Instruments. Ensure the specific suffix FC corresponds to the required flatpack variant and check RoHS compliance status against current regulatory requirements. Confirm availability through authorized distributors handling legacy or acquired product lines.

Selection Notes

Select this component when a single IC must replace multiple discrete gates to save board space. The 19-input capacity allows complex logic reduction. Verify that the 24-CFlatpack footprint matches the PCB layout constraints. Consider the 100K series speed and power characteristics relative to the system's timing requirements before finalizing the design.

Part Context

This part belongs to the National Semiconductor 100K series of high-speed CMOS logic devices. The series provides versatile logic functions in standardized packages. As National Semiconductor's semiconductor division was acquired by Texas Instruments, support and documentation may now be managed under the TI portfolio, affecting long-term sourcing strategies.

Replacement Considerations

Check for direct equivalents in the Texas Instruments SN74HC or SN74HCT series if pin compatibility allows. Verify logical equivalence for the specific AND/OR configuration needed. Legacy stock may still be available from third-party suppliers.
