Overview
The 100171DCQR is a triple 4-input multiplexer belonging to the ECL100 series, manufactured by National Semiconductor. It features three independent functions, each accepting four data lines and providing one primary output along with a complementary output. The device utilizes ECL logic family technology and is housed in a CDIP24 package with 24 pins. It operates within a temperature range of 0 to 85 degrees Celsius.
Feature Summary
- Triple independent multiplexing functionality
- ECL100 series logic compatibility
- Complementary output configuration
Applications
- High-speed digital signal routing
- Data selection in ECL-based systems
- Multiplexing applications requiring complementary outputs
Procurement Notes
Verify the manufacturer designation as National Semiconductor, now part of Texas Instruments, due to corporate acquisitions. Confirm the specific suffix 'DCQR' corresponds to the commercial temperature grade and ceramic DIP packaging. Ensure compatibility with existing ECL power supply requirements and termination networks before procurement.
Selection Notes
Select this component when triple 4-to-1 multiplexing is required within an ECL100 architecture. The CDIP24 package suits through-hole mounting needs. Consider the complementary output feature if differential signaling or inversion is necessary without additional gates. Verify thermal performance within the specified 0 to 85 degrees Celsius range for the intended environment.
Part Context
This part belongs to the National Semiconductor 100K series of high-speed ECL logic devices. These components are designed for applications demanding fast switching speeds and low propagation delay. The 100171 specifically addresses the need for multiple independent multiplexing channels in a single package, reducing board space compared to discrete solutions.
Replacement Considerations
Check for direct equivalents from Texas Instruments following the acquisition of National Semiconductor. Verify pinout and electrical characteristics against other ECL100 triple multiplexers if sourcing from alternative vendors. Ensure the replacement supports the same CDIP24 form factor if physical constraints are critical.
