Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Note 1: Pin must be AC-coupled with a DC blocking capacitor.
CAUTION! ESD SENSITIVE DEVICE
DC Electrical Characteristics
(VCC = +2.7V to +5.5V, TA = -40°C to +85°C (MAX2640EUT/MAX2641EUT), TA = -40°C to +125°C (MAX2640AUT), unless otherwise
noted. Typical values are at VCC = +3.0V, TA = +25°C.) Limits at TA = +25°C are guaranteed by production test. Limits over temperature
are guaranteed by design and characterization.
