MC10EP57DTG

Overview

The MC10EP57DTG is a fully differential 4:1 multiplexer from the MC10EP series, manufactured by onsemi. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V and VEE at 0 V, or in NECL mode with VCC at 0 V and VEE ranging from -3.0 V to -5.5 V. The device features typical propagation delays of 375 ps and supports maximum frequencies exceeding 2 GHz. It includes internal input pulldown resistors, safety clamps, and multiple VBB outputs for reference voltage generation. The component is housed in a TSSOP-20 package.

Feature Summary

• Fully differential architecture designed for low skew applications such as clock distribution
• Configurable as either a 4:1 or 2:1 multiplexer depending on select line configuration
• Includes internal safety clamps and open input default states for system stability
• Provides internally generated VBB reference voltage outputs for AC coupling rebiasing

Applications

• Clock distribution networks requiring low skew performance
• High-speed data routing in ECL-based digital systems
• Differential signal selection in telecommunications infrastructure

Procurement Notes

Verify current availability status directly with onsemi or authorized distributors, as specific variants within this family may be discontinued. Confirm that the DTG suffix corresponds to the TSSOP-20 package required for your design. Ensure compliance with RoHS standards and lead-free requirements before finalizing procurement orders.

Selection Notes

Select the MC10EP57DTG when a fully differential 4:1 multiplexer is required for high-speed ECL applications. Consider the MC100EP57 variant if temperature compensation is necessary for operation across wider thermal ranges. Verify power supply compatibility with either PECL or NECL logic levels based on system voltage constraints.

Part Context

This component belongs to the MC10EP series of ECL logic devices produced by onsemi. It is functionally related to the MC100EP57, which offers enhanced temperature compensation characteristics. The device is part of a broader portfolio of high-speed differential logic components designed for demanding timing and signal integrity applications.

Replacement Considerations

The MC100EP57DTG serves as a direct functional replacement offering temperature compensation. Verify pinout compatibility and ensure that the absence of temperature compensation in the standard EP57 does not impact system reliability under varying thermal conditions.
