(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground
except: V

(2) All typical values are given for: V
DD
= +3.3 V, T
A
= +25°C.
(3) The DS90LV049Q drivers are current mode devices and only function within datasheet specifications when a resistive load is applied to
their outputs. The typical range of the resistor values is 90 Ω to 110 Ω.
(4) Output short circuit current (I
OS
) is specified as magnitude only, minus sign indicates direction only.
(5) Both driver and receiver inputs are static. All LVDS outputs have 100 Ω load. All LVCMOS outputs are floating. None of the outputs
have any lumped capacitive load.
