Operating Temperature Range
MAX1601EAI/MAX1604EAI .............................-40°C to +85°C
Storage Temperature Range .............................-65°C to +160°C
Lead Temperature (soldering, 10sec) .............................+300°C
Note 1: There are no parasitic diodes between any of these pins, so there are no power-up sequencing restrictions (for example,
logic input signals can be applied even if all of the supply voltage inputs are grounded).
Note 2: VCC and VPP outputs are internally current-limited to safe values. See the Electrical Characteristics table.
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.
