The EL1056 is designed to drive highquality test signals into close or terminated loads. It has a dispersion of 250ps 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.
The output can be turned off in two ways; the OE pins allow the output to be put in a high-impedance state which makes the output look like a large resistance in parallel with 3pF, even for back-driven signals with as much as 2.5V/s slew rate. The E pins put the output in an even higher impedance state, guaranteed to 150nA leakage in the EL1056A. This allows accurate measurements on the bus without disconnecting the EL1056 with a relay.
The EL1056 incorporates an output current sense which can warn the system controller that excessive output current is flowing. The trip point is set by two external resistors.
