POST OFFICE BOX 655303
DALLAS, TEXAS 75265
APPLICATION INFORMATION
In most applications, it is not customary to have a common-mode input close to ground and to have a differential
voltage larger than 2 V. Since the common-mode input voltage is typically around 1.5 V, a 2-V V
ID
would result
in a V
IL
of 0.5 V, thus satisfying the recommended V
IL
level of greater than 0.4 V.
Figure 8 plots seven different input threshold curves from a variety of production lots and shows how the fail-safe
circuitry behaves with the input common-mode voltage levels. These input threshold curves are representative
samples of production devices. The curves specifically illustrate a typical range of input threshold variation. The
AM26LV32 is specified with
±
200 mV of input sensitivity to account for the variance in input threshold. Each data
point represents the input’s ability to produce a known state at the output for a given V
IC
and V
ID
. Applying a
differential voltage at or above a certain point on a curve would produce a known state at the output. Applying
a differential voltage less than a certain point on a curve would activate the fail-safe circuit and the output would
be in a high state. For example, inspecting the top input threshold curve reveals that for a V
IC
1.6 V, V
ID
yields
around 87 mV. Applying 90 mV of differential voltage to this particular production lot generates a known receiver
output voltage. Applying a V
ID
of 80 mV activates the input fail-safe circuitry and the receiver output is placed
in the high state. Texas Instruments specifies the input threshold at
±
200 mV, since normal process variations
affect this parameter. Note that at common-mode input voltages around 0.2 V, the input differential voltages are
low compared to their respective data points. This phenomenon points to the fact that the inputs are very
sensitive to small differential voltages around 0.2 V V
IC
. It is recommended that V
IC
levels be kept greater than
0.5 V to avoid this increased sensitivity at V
IC
0.2 V. In most applications, since V
IC
typically is 1.5 V, the
fail-safe circuitry functions properly to provide a high state at the receiver output.
