100165DCQR

Overview

The 100165DCQR is an encoder integrated circuit manufactured by National Semiconductor, belonging to the 100K series. It functions as a 1 x 8:4 encoder, converting eight input lines into four binary output lines. The component is housed in a 24-CDIP package, which provides a dual in-line configuration with 24 pins for circuit integration. This device is designed for signal encoding applications within electronic systems requiring reliable data conversion from multiple inputs to a compressed binary format.

Feature Summary

• Performs 8-to-4 line encoding functionality
• Housed in a 24-pin dual in-line ceramic package

Applications

• Digital signal encoding circuits
• Data compression interfaces
• Binary output generation systems

Procurement Notes

Verify manufacturer authenticity as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'DCQR' matches required packaging and material specifications. Ensure compatibility with existing 24-CDIP footprints on printed circuit boards. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate that the 100K series designation aligns with system performance requirements.

Selection Notes

Select this component when an 8-input to 4-output encoding function is required in a robust ceramic package. The 24-CDIP form factor suits through-hole mounting techniques. Consider the 100K series characteristics for speed and power consumption needs. Ensure the design accommodates the physical dimensions of the dual in-line package. Verify interface logic levels match system voltage standards.

Part Context

National Semiconductor specialized in analog and mixed-signal integrated circuits before being acquired by Texas Instruments. The 100K series represents a family of logic devices known for specific performance characteristics. This encoder falls under the signal switches and multiplexers category, serving as a fundamental building block for digital logic systems requiring input consolidation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 8-to-4 encoders in CDIP-24 packages only after verifying pinout and electrical parameter compatibility.
