Abstract
A differential ECL signal is converted to a first current and a second current that are proportional to the ECL signal. An upper output transistor (16) and a lower output transistor (57) are selectively enabled and disabled by the first current. The second current is used to enable discharging of a storage capacitance of the lower output transistor (57) thereby substantially disabling the lower output transistor (57) before the upper output transistor (16) is enabled. In addition, a capacitor is used to momentarily discharge the storage capacitance as the upper output transistor (16) is enabled. The capacitor is discharged when the upper output transistor (16) is disabled.
