Note 1: Stresses beyond those listed under Absolute Maximum Ratings 
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Internal clamps limit the SCL, SDA (LTC4151) and SDAI  
(LTC4151-1/LTC4151-2) pins to a minimum of 5.5V. Driving these pins to
voltages beyond the clamp may damage the part. The pins can be safely
tied to higher voltages through a resistor that limits the current below
5mA.

The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T
A
 = 25癈. V
IN
 is from 7V to 80V, unless noted. (Note 3)
Note 3: All currents into pins are positive. All voltages are referenced to 
GND, unless otherwise noted.
Note 4: Guaranteed by design and not subject to test.
Note 5: Integral nonlinearity and total unadjusted error of V
IN
 are tested
between 7V and 80V.
Note 6: Offset error of V
IN
 is defined by extrapolating the straight line
measured between 7V and 80V.
