Monolithic High-Speed Pin Driver
The EL1056 is designed to drive high-
quality 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/µs 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.
