SY54020AR - Micrel Semiconductor

SY54020AR Low Voltage 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer

The SY54020AR is a fully differential, low voltage 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with active-low Enable (/EN). The Enable is synchronous so that the outputs will only be enabled/disabled when they are already in the LOW state. This avoids any chance of generating a runt clock pulse when the device is enabled/disabled as can happen with an asynchronous.
