General Description

The EL1056 is designed to drive high-quality test signals into close or terminated loads. It has a dispersion of 250 ps or less — whether due to signal size or direction of edge. It can output a very wide 24V output span, encompassing all logic families as well as analog levels. The EL1056 is fabricated in Elantec’s oxide isolated process, which eliminates the possibility of latch-up and provides a very durable circuit.
