MC100EP11D

Clock Buffers, Drivers Overview

The MC100EP11D is a high-speed, differential 1:2 fanout buffer manufactured by onsemi. Designed for ECL logic families, it operates with supply voltages of 3.3V or 5V. The device accepts a differential input and provides two complementary outputs (Q and Q_bar). It is housed in an 8-SOIC surface-mount package. The component supports maximum frequencies exceeding 3.0 GHz and features typical propagation delays around 240 ps. It includes open-input default state protection, ensuring the Q output defaults to LOW if inputs are left floating.

Clock Buffers, Drivers Feature Summary

• Differential 1:2 fanout buffer architecture
• Supports 3.3V and 5V ECL power supplies
• Maximum operating frequency > 3.0 GHz
• Typical propagation delay of 240 ps
• Open input default state protection

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• ECL-based system timing circuits
• Differential signal buffering in telecommunications equipment

Clock Buffers, Drivers Part Context

The MC100EP11D belongs to the MC10/100EP series of ECL components. It is functionally equivalent to the MC10EP11 but includes temperature compensation characteristics associated with the 100 Series. This distinguishes it from the standard 10 Series devices which may lack such compensation. The 'D' suffix indicates the 8-SOIC package variant.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers include MC100EP11DT (TSSOP-8 package) and MC100EP11DTR2 (Tape & Reel packaging). These variants share identical electrical specifications and pinouts, differing only in physical packaging format.
