MC10173P

Overview

The MC10173P is a quad 2-input multiplexer/latch manufactured by onsemi. It operates within the ECL logic family, designed for high-speed signal routing and latching applications. The device features four independent multiplexers with latch functionality, supporting differential or single-ended inputs depending on configuration. It is housed in a standard DIP package suitable for through-hole mounting. Key electrical characteristics include operation with negative supply voltages typical of ECL circuits, ensuring fast switching speeds and low propagation delay. The component is rated for industrial temperature ranges, making it suitable for demanding electronic environments requiring reliable data selection and storage.

Feature Summary

• Integrates four independent 2-to-1 multiplexers with built-in latch capability for simultaneous data selection and storage
• Utilizes ECL technology to achieve high-speed switching performance and minimal propagation delay
• Provides flexible input handling compatible with differential signaling configurations common in high-frequency systems

Applications

• High-speed data routing in telecommunications equipment
• Signal multiplexing in computer memory systems
• Clock distribution networks requiring precise timing control

Procurement Notes

Verify the specific suffix code on the component marking to confirm package type and temperature grade, as variations may exist within the MC10173 series. Ensure compatibility with existing ECL power supply rails, typically requiring negative voltage references. Confirm that the target PCB layout supports the required pin pitch and thermal dissipation for the selected package style. Cross-reference the manufacturer's latest datasheet for any updates on mechanical dimensions or recommended soldering profiles to ensure assembly integrity.

Selection Notes

Select this component when system design requires multiple independent 2-input selection paths with latching behavior in a single package. It is appropriate for designs utilizing ECL logic families where speed is critical. Consider the power supply requirements, specifically the need for negative voltage rails, before implementation. Evaluate the pin count and package footprint against available board space. This part is ideal for replacing older discrete multiplexer solutions to reduce component count and simplify routing in complex digital architectures.

Part Context

The MC10173P belongs to onsemi's extensive portfolio of high-speed logic devices, specifically within the ECL (Emitter-Coupled Logic) category. This family is known for superior performance at high frequencies compared to TTL or CMOS alternatives. The device serves as a fundamental building block for data path management in legacy and specialized high-speed digital systems. Its inclusion in the product line supports applications needing robust signal integrity and fast response times without the complexity of external latching circuitry.

Replacement Considerations

Check for direct cross-references from other manufacturers offering quad 2-input ECL multiplexers/latches. Verify pinout compatibility if substituting with similar parts from different vendors. Ensure the replacement device meets the same speed and voltage specifications to maintain system performance.
