MC100E158FN

Overview

The MC100E158FN is a high-speed 5-bit 2:1 multiplexer from the onsemi 100E series, designed for 5V ECL applications. It operates within a supply voltage range of 4.2 V to 5.7 V and supports differential inputs and outputs. The device features temperature compensation for stable performance across varying thermal conditions. Packaged in a 28-PLCC surface-mount format, it is suitable for demanding clock distribution and data routing tasks requiring fast switching speeds.

Feature Summary

• Provides five independent 2:1 multiplexing channels with differential signal handling capabilities.
• Incorporates internal temperature compensation to maintain consistent electrical characteristics across operating temperatures.
• Supports flexible power supply configurations including PECL mode operation.

Applications

• High-speed clock signal routing and distribution networks
• Data bus selection and multiplexing in communication systems
• Test and measurement equipment requiring precise signal path control

Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm package integrity as moisture sensitivity level requires proper handling. Check for RoHS compliance variations between manufacturing lots. Ensure replacement parts match pinout and electrical specifications exactly. Validate supplier documentation against original datasheet revisions.

Selection Notes

Choose this component when differential ECL signaling is required for low-noise high-speed applications. Consider the 28-PLCC package for surface-mount assembly constraints. Evaluate thermal management needs given the temperature-compensated design benefits. Compare propagation delay specifications against system timing requirements. Assess power supply stability within the specified 4.2 V to 5.7 V range.

Part Context

Part of the MC100E family offering enhanced performance over standard ECL logic. Designed for applications requiring reliable high-frequency operation with minimal skew. Shares architectural similarities with other 100E series devices while providing specific multiplexing functionality. Manufactured using processes optimized for speed and power efficiency in ECL environments.

Replacement Considerations

MC10E158FN serves as a direct functional equivalent with identical pinout and specifications. MC10E158FNG offers lead-free packaging options while maintaining electrical compatibility. Verify that substitute components support the same 5V ECL operating voltages and differential output requirements.
