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
Applications
Memory testers
ASIC testers
Functional board testers
Analog digital incoming
component verifiers
Logic emulators
