MAX9386EUP+T

Overview

The MAX9386EUP+T is a fully differential, high-speed ECL/PECL multiplexer with a single output buffer. It features a 5:1 mux architecture and operates within a supply voltage range of 2.375V to 5.5V. The device provides extremely low propagation delays of 318ps typical and output-to-output skews of 3.9ps typical for the dual-buffer variant. It supports toggle frequencies exceeding 2.7GHz and includes internal biasing circuits that ensure low-default output states when inputs are left open.

Feature Summary

• Fully differential ECL/PECL multiplexing with integrated output buffering
• Extremely low propagation delay and minimal output skew for precise timing
• Internal pulldowns on select inputs ensure default low state if left unconnected
• On-chip reference outputs allow configurable single-ended input operation

Applications

• Central office backplane clock distribution
• DSLAM/DLC applications
• High-speed telecom and datacom systems

Procurement Notes

Verify the component matches the specific 20-pin TSSOP package configuration required for your design. Confirm that the operating temperature range aligns with your environmental specifications. Ensure proper bypassing capacitors are utilized near the power pins to maintain signal integrity at high speeds.

Selection Notes

Select this part for designs requiring a 5:1 mux topology with a single differential output. Consider the MAX9387 if redundant dual output buffers are necessary for system reliability. Verify that the logic levels of your select inputs are compatible with the internal VBB reference voltage.

Part Context

This component belongs to the MAX9386/MAX9387/MAX9388 family of high-speed multiplexers. While the MAX9386 offers a single buffer, the MAX9387 provides dual buffers for redundancy, and the MAX9388 serves as a pin-compatible 4:1 alternative. All variants share similar electrical characteristics and packaging options.

Replacement Considerations

The MAX9388 is explicitly noted as pin compatible with the MC100EP57. No other direct substitute part numbers are confirmed in the provided documentation.
