(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground
unless otherwise specified.
(2) All typicals are given for: V_CC = +3.3V, T_A = +25°C.
(3) V_CC is always higher than R_IN+ and R_IN− voltage. R_IN− and R_IN+ are allowed to have a voltage range −0.2V to V_CC− VID/2. However, to
be compliant with AC specifications, the common voltage range is 0.1V to 2.3V
(4) The VCMR range is reduced for larger VID. Example: if VID = 400mV, the VCMR is 0.2V to 2.2V. The fail-safe condition with inputs
shorted is not supported over the common-mode range of 0V to 2.4V, but is supported only with inputs shorted and no external
common-mode voltage applied. A VID up to V_CC− 0V may be applied to the R_IN+/ R_IN− inputs with the Common-Mode voltage set to
V_CC/2. Propagation delay and Differential Pulse skew decrease when VID is increased from 200mV to 400mV. Skew specifications
apply for 200mV ≤ VID ≤ 800mV 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.
