The MC10E/100E211 is a low skew 1:6 fanout device designed explicitly for low skew clock distribution applications. The device can be driven by either a differential or single-ended ECL or, if positive power supplies are used, PECL input signal (PECL is an acronym for Positive ECL, PECL levels are ECL levels referenced to +5V rather than ground). If a single-ended input is to be used the VBB pin should be connected to the CLK input and bypassed to ground via a 0.01µF capacitor. The VBB supply is designed to act as the switching reference for the input of the E211 under single-ended input conditions, as a result this pin can only source/sink up to 0.5mA of current.
The Motorola MC10E211 and MC100E211 are low skew 1:6 fanout devices designed explicitly for low skew clock distribution applications. They can be driven by either a differential or single-ended ECL input signal, or if positive power supplies are used, a PECL (Positive ECL) input signal.
Key features include synchronous enabling/disabling of outputs to avoid runt pulse generation during disable operations, multiplexed clock inputs for distributing lower speed scan clocks alongside high-speed system clocks, and internal 75kΩ input pulldown resistors. The devices offer both common and individual enable/disable control with high bandwidth output transistors.

It is designed explicitly for low skew clock distribution applications.
Yes, if positive power supplies are used, it can accept PECL (Positive ECL) input signals.
Outputs are enabled/disabled only when they are already in the LOW state to avoid runt pulse generation.
