ELECTRICAL CHARACTERISTICS
The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.
2.7V ≤ VCC ≤ 5.5V, VID25 = VID0 = VID1 = VID2 = VID3 = NC unless otherwise noted. (Note 3)

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All voltages are with respect to GND pin.
Note 3: The LTC1706-85 is guaranteed to meet performance specifications
from 0°C to 70°C. Specifications over the – 40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 4: Supply current is specified with all VID inputs floating. Due to the
internal pull-ups on the VID pins, the supply current will increase
depending on the number of grounded VID lines. Each grounded VID line
will draw approximately [(VCC – 0.6)/40]mA. If the VID inputs are left
unconnected, they will float to VCC at a rate controlled by parasitic
capacitance. Until the VID inputs reach their final states, slightly higher
IVCC current may be observed. (See the Operation section for more detail.)
Note 5: Each built-in pull-up resistor attached to the VID inputs also has a
series diode connected to VCC to allow input voltages higher than the VCC
supply without damage or clamping. (See Operation section for further
details.)
