Notes:
1. The RST and Cn inputs of the device must be held at valid levels (not floating) to ensure proper device operation. The differential inputs must
not be floating, unless RST is low.
Notes:
1. Stresses greater than those listed under MAXIMUM
RAINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions above those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect reliability.
2. The input and output negative-voltage ratings may be ex-
ceeded if the input and output clamp-current ratings are
observed.
3. This value is limited to 2.5V maximum
