MC10166P

Comparators Overview

The MC10166P is a 5-bit magnitude comparator from the onsemi MC10100 series, designed for high-speed digital logic applications. It features differential inputs and bit-level outputs to compare two 5-bit binary words. The device operates within a negative supply voltage range of -4.2 V to -5.7 V, typical for ECL logic families. It utilizes the MOSAIC III process to ensure low propagation delay and high noise immunity. The component is housed in a 16-pin PDIP package and includes internal input pull-down resistors for stable operation when inputs are floating.

Comparators Feature Summary

• Provides five independent bit outputs for direct comparison of two 5-bit binary numbers
• Utilizes differential input architecture with dedicated VCCO supply leads for each receiver stage
• Incorporates internal 50 kΩ pull-down resistors on inputs to prevent undefined states
• Built using MOSAIC III process technology for enhanced common-mode noise rejection

Comparators Applications

• High-speed digital data path comparison circuits
• Address decoding systems requiring rapid magnitude verification
• Control logic for sorting or ranking operations in embedded systems
• Interface circuits between different logic families requiring level translation

Comparators Procurement Notes

Verify the specific suffix 'P' indicates the PDIP-16 plastic DIP package configuration. Confirm RoHS compliance status as historical data may vary by production batch. Ensure the design supports negative supply voltages consistent with ECL standards. Check for lead-free availability if required by current manufacturing regulations. Validate pinout compatibility with existing PCB footprints before integration.

Comparators Selection Notes

Select this component when bit-wise output granularity is required rather than a single greater/less/equal signal. Consider the MC10166P for designs needing fast response times in ECL environments. Evaluate power consumption against system thermal constraints due to inherent ECL characteristics. Compare against CMOS alternatives if lower voltage operation is necessary for the target application.

Comparators Part Context

This part belongs to the MC10100 series of high-speed ECL logic devices manufactured by onsemi. The series is known for utilizing advanced bipolar processes to achieve nanosecond switching speeds. These components are typically used in telecommunications and networking equipment where signal integrity and speed are critical. The MC10166P specifically addresses the need for parallel data comparison in high-frequency digital architectures.

Comparators Replacement Considerations

Check for MC10166L or other suffix variants for minor packaging or temperature grade differences. Verify functional equivalence with other 5-bit comparators if sourcing from alternative manufacturers. Ensure replacement parts maintain compatible ECL voltage levels and output drive capabilities.
