MC10EP57DTR2

Overview

The MC10EP57DTR2 is a high-performance differential digital multiplexer from onsemi's 10EP series. It functions as a 4:1 multiplexer, or a 2:1 multiplexer when the SEL1 input is pulled low. The device supports dual power supplies ranging from ±3V to ±5.5V, compatible with PECL and NECL logic families. It features a typical propagation delay of 375 ps and operates at frequencies exceeding 2 GHz. The component is housed in a 20-TSSOP package with an exposed pad for thermal management.

Feature Summary

• Full-differential architecture designed for low-skew applications such as clock distribution
• Configurable operation as either a 4:1 or 2:1 multiplexer via SEL1 pin configuration
• Internal VBB reference voltage generation for AC coupling biasing and single-ended input conversion
• Input safety clamping with open-input default state ensuring Q output defaults to low level

Applications

• Clock distribution networks requiring low skew
• High-speed data routing systems
• PECL/NECL logic interface circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure the selected variant matches the required operating temperature range and RoHS compliance status. Cross-reference the part number with official distributor catalogs to confirm current availability and manufacturing status before finalizing procurement plans.

Selection Notes

Select this component for designs requiring differential signal integrity and high-speed switching capabilities within ECL-compatible voltage ranges. Consider the 20-TSSOP package constraints for PCB layout and thermal dissipation requirements. Evaluate the need for internal VBB reference usage if AC coupling or single-ended conversion is required in the signal path.

Part Context

This device belongs to the onsemi 10EP series of emitter-coupled logic components. It shares functional similarities with the MC100EP57 but differs in temperature rating and packaging options. The series is engineered for robust performance in high-frequency digital applications where signal fidelity and timing precision are critical design parameters.

Replacement Considerations

MC100EP57DTG is listed as a parameter-equivalent substitute.
