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 ox-
ide 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 3 pF even for
back-driven signals with as much as 2 5V ms slew rate The E
pins put the output in an even higher impedance state guaran-
teed to 150 nA 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
