MC10EP11DT

Clock Buffers, Drivers Overview

The MC10EP11DT is a discontinued differential 1:2 fanout buffer from the onsemi 10EP series, housed in an 8-lead TSSOP package. It provides high-speed clock distribution with a typical propagation delay of 220 ps and a maximum frequency exceeding 3 GHz. The device supports PECL operation (VCC = 3.0 V to 5.5 V) and NECL operation (VEE = −3.0 V to −5.5 V). Key electrical characteristics include a typical power supply current of 29 mA at 25°C for the 10EP variant, safety clamps on inputs, and open-input default states where Q outputs go LOW.

Clock Buffers, Drivers Feature Summary

• Differential 1:2 fanout buffer with 220 ps typical propagation delay
• Maximum clock frequency > 3 GHz typical
• Supports PECL (3.0 V–5.5 V) and NECL (−3.0 V to −5.5 V) modes
• Safety clamps on inputs; Q outputs default LOW when inputs are open

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• PECL/NECL logic system interconnects
• Differential signal buffering in telecommunications equipment

Clock Buffers, Drivers Procurement Notes

The MC10EP11DT is listed as discontinued in the official datasheet and is not recommended for new designs. Verification of availability should be restricted to existing stock or secondary market sources, as original manufacturer production has ceased. Designers must confirm end-of-life status before integration into new hardware.

Clock Buffers, Drivers Selection Notes

Select this component only for legacy board maintenance or replacement of existing MC10EP11DT units. For new designs, consult the ordering information table for active alternatives such as the MC100EP11DTG or MC10EP11DG. Ensure voltage requirements match the specific 10EP vs. 100EP DC characteristics if substituting within the family.

Clock Buffers, Drivers Part Context

This part belongs to the MC10EP11 family of ECL fanout buffers. The 'DT' suffix specifically denotes the TSSOP-8 package (CASE 948R-02). The datasheet explicitly categorizes the MC10EP11DT under the 'DISCONTINUED' section, distinguishing it from active variants like the MC100EP11DTG which remains available in the same package.

Clock Buffers, Drivers Replacement Considerations

The datasheet identifies the MC100EP11DTG as an active alternative in the same TSSOP-8 package. While functionally similar, the 100 Series includes temperature compensation and slightly different DC characteristics (e.g., higher typical IEE of 35 mA vs. 29 mA for the 10EP series). Verify pin compatibility and thermal performance when substituting.
