MC10H166P

Comparators Overview

The MC10H166P is a 5-bit magnitude comparator from the onsemi 10H series. It provides three active-high outputs indicating A < B, A > B, and A = B relationships between two 5-bit binary inputs. The device operates on a single -5V supply within a voltage range of -4.9V to -5.46V. It is housed in a 16-pin PDIP package with a lead pitch of 0.300 inches (7.62mm). The component supports surface mount or through-hole installation styles depending on variant, though this specific model uses DIP. It functions at clock frequencies up to 250 MHz.

Comparators Feature Summary

• Provides simultaneous comparison results for two 5-bit binary words
• Generates distinct active-high logic signals for less than, greater than, and equal conditions
• Operates using standard -5V ECL power supplies

Comparators Applications

• Digital signal processing systems requiring parallel data comparison
• Address decoding circuits in high-speed computing architectures
• Control logic for sorting algorithms in embedded systems

Comparators Procurement Notes

Verify RoHS compliance status carefully as documentation indicates potential non-compliance for certain manufacturing dates. Confirm package integrity upon receipt. Check for End-of-Life notifications or discontinuance notices prior to final design approval. Ensure supply chain sources are authorized distributors to avoid counterfeit components. Validate pinout compatibility if substituting into existing PCB layouts.

Comparators Selection Notes

Select this component when a dedicated 5-bit magnitude comparison function is required in high-speed digital designs. It is suitable for applications needing immediate determination of inequality or equality between two data streams. Consider the 10H series speed-power trade-offs against other logic families. Ensure the system can provide stable negative voltage regulation for proper ECL operation.

Comparators Part Context

This part belongs to the onsemi 10H series of high-speed ECL logic devices. The series is designed for applications demanding fast propagation delays and high-frequency operation. The MC10H166P specifically addresses the need for parallel data comparison without external logic gates. It complements other 10H family members like decoders and buffers in complex digital systems.
