Applications Information
to some ECL and PECL devices, but without the heavy static
I
cations for the driver are a tenfold improvement over other
existing RS-422 drivers.
The fail-safe circuitry guarantees that the outputs are en-
abled and at a logic ’0’ (the true output is low and the
complement output is high) when the inputs are floating.
The TRI-STATE function allows the driver outputs to be
disabled, thus obtaining an even lower power state when the
transmission of data is not required.

The footprint of the DS90C031B is the same as the industry
standard 26LS31 Quad Differential (RS-422) Driver.
The DS90C031B is electrically similar to the DS90C031, but
differs by supporting high impedance LVDS outputs under
power-off condition. This allows for multiple or redundant
drivers to be used in certain applications. The DS90C031B is
offered in a space saving narrow SOIC (150 mil.) package.
