MC10E154FN

Overview

The MC10E154FN is a 5-bit 2:1 multiplexer latch from the onsemi MC10E logic series, designed for high-speed digital applications. It operates within a supply voltage range of -4.2 V to -5.7 V and features a propagation delay of 0.8 ns at 5 V. The device is housed in a 28-lead PLCC package with surface mount installation. It supports an operating temperature range from 0°C to +85°C and contains ten internal circuits configured as mux latches.

Feature Summary

• Integrates five independent 2-to-1 multiplexers with latch functionality for data selection and storage.

Applications

• High-speed digital signal routing systems
• Data acquisition circuitry requiring fast switching
• Telecommunications equipment signal processing

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and moisture sensitivity handling requirements before assembly. Cross-reference datasheet specifications against current design constraints to ensure compatibility with existing power and timing parameters.

Selection Notes

Select this component when designing systems requiring low propagation delay and differential ECL signaling. Ensure power supply rails match the specified negative voltage range. Consider the PLCC footprint constraints during PCB layout planning to maintain signal integrity and thermal performance standards.

Part Context

This part belongs to the MC10E family of emitter-coupled logic devices manufactured by onsemi. It serves as a specialized variant within the broader multiplexer and latch category, offering specific bit-width configurations for complex data path management in professional electronic hardware designs.

Replacement Considerations

MC10E154FNR2G is a verified tape-and-reel alternative from the same manufacturer. Verify pinout compatibility and electrical parameter alignment before substituting in existing board layouts.
