(1) Current into device pin is defined as positive. Current out of the device is defined as negative. All voltages are referenced to ground,
unless otherwise specified.
(2) All typical values are at 25°C and with a 3.3-V supply.

is always higher than R

voltage, R

and R

have a voltage range of -0.2 V to V

ID
/2. To be compliant with ac
specifications the common voltage range is 0.1 V to 2.3 V.
(4) The VCMR range is reduced for larger V
ID
, Example: If V
ID
= 400 mV, the VCMR is 0.2 V to 2.2 V. The fail-safe condition with inputs
shorted is not supported over the common-mode range of 0 V to 2.4 V, but is supported only with inputs shorted and no external
common-mode voltage applied. A V
ID
up to V
CC
-0 V may be applied to the R
IN+
and R
IN-
inputs with the common-mode voltage set to
V
CC
/2. Propagation delay and differential pulse skew decrease when V
ID
is increased from 200 mV to 400 mV. Skew specifications
apply for 200 mV < V
ID
< 800 mV over the common-mode range.
(5) Output short circuit current (I
OS
) is specified as magnitude only, minus sign indicates direction only. Only one output should be shorted
at a time. Do not exceed maximum junction temperature specification.
