MC100EP57DT

Overview

The MC100EP57DTG is a fully differential 4:1 multiplexer from the onsemi MC100EP series, housed in a TSSOP-20 surface-mount package. It supports PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE ranging from -3.0 V to -5.5 V (VCC = 0 V). The device features typical propagation delays of 375 ps and a maximum frequency exceeding 2 GHz. It includes internal temperature compensation, open input default states, safety clamps on inputs, and multiple VBB outputs for reference voltage generation.

Feature Summary

• Fully differential architecture designed for low skew applications such as clock distribution
• Configurable as either a 4:1 or 2:1 multiplexer by leaving the SEL1 line open
• Includes internal temperature compensation for stable performance across operating temperatures
• Provides multiple VBB outputs that can be used as switching reference voltages or to rebias AC coupled inputs

Applications

• Clock distribution systems requiring low skew
• High-speed data routing in telecommunications equipment
• Signal selection in complex digital logic circuits

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to ensure correct packaging and compliance status. Confirm whether the specific variant is recommended for new designs or if it has been discontinued. Check for RoHS compliance and lead-free certification requirements relevant to your manufacturing process before finalizing procurement.

Selection Notes

Select this component when a fully differential ECL multiplexer with high speed and low skew is required. Ensure the system power supply matches either the PECL or NECL operating range specified in the datasheet. Consider the thermal resistance characteristics and the need for an exposed pad connection if using the QFN variant, though this part uses TSSOP-20.

Part Context

This device belongs to the MC100EP family of ECL logic components manufactured by onsemi. The '100' prefix indicates the inclusion of temperature compensation features compared to the standard MC10EP series. It is part of a broader portfolio of high-speed differential logic devices designed for demanding signal processing and timing applications.

Replacement Considerations

MC10EP57DTG serves as the non-compensated equivalent within the same package. MC100EP57DTR2G offers the same functionality but in a tape and reel format instead of rail packaging.
