ELECTRICAL CHARACTERISTICS
At TA = +25°C, VDD = 5V, load resistance = 500 on each output to ground differential output (2Vp-p), MGS = 011, and fIN = 5MHz, unless otherwise noted.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
