(1) The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as
otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and
are not ensured.
(2) 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
OD
and ΔV
OD
.
(3) Typical values represent most likely parametric norms for V
CC
= +3.3V and T
A
= +25°C, and at the Recommended Operation Conditions
at the time of product characterization and are not ensured.
(4) Output short circuit current (I
OS
) is specified as magnitude only, minus sign indicates direction only.
(5) Input Differential Voltage (V
ID
) The DS25BR100 limits input amplitude to 1 volt. The DS25BR101 supports any V
ID
within the supply
voltage to GND range.
(6) Input Termination Resistor (R
IN
) The DS25BR100 provides an integrated 100 ohm input termination for the high speed LVDS pair. The
DS25BR101 eliminates this internal termination.
