MC10EP57MNTXG

Overview

The MC10EP57MNTXG is a differential digital multiplexer from onsemi, belonging to the 10EP series. It functions as a 1 x 4:1 multiplexer with dual power supply operation ranging from ±3V to ±5.5V. The device utilizes a 20-VFQFN exposed pad package and supports surface mount installation. It operates within a temperature range of -40°C to +85°C. The component is classified as obsolete and no longer manufactured.

Feature Summary

• Full-differential architecture designed for low skew applications such as clock distribution.
• Capable of operating as a 4:1 multiplexer or reconfigured as a 2:1 multiplexer when SEL1 is pulled low.
• Includes internal VBB outputs for AC coupling input re-biasing and single-ended reference voltage generation.

Applications

• Clock distribution networks requiring low skew performance.
• High-speed data routing in telecommunications systems.
• Signal selection in differential ECL logic circuits.

Procurement Notes

This component is officially discontinued and marked as obsolete by the manufacturer. No new production units are available. Engineers must verify end-of-life notifications and consult official discontinuance documents before finalizing designs. Sourcing should focus on identifying parameter-equivalent replacement parts that meet the required electrical specifications and pinout compatibility.

Selection Notes

Designers should consider the transition from tube packaging to tape-and-reel formats within this family when evaluating availability. Verify that the specific MN suffix corresponds to the QFN-20 package variant. Ensure that the application environment remains within the specified -40°C to +85°C operating range and that power supply rails align with the ±3V to ±5.5V requirements for proper ECL functionality.

Part Context

The MC10EP57MNTXG is part of the MC10EP57 family of high-performance differential multiplexers. It shares functional characteristics with the MC100EP57 series, though it lacks the temperature compensation features found in the 100-series variants. This component represents a legacy solution for fast differential signal switching in older high-speed digital designs.
