MAX6576/MAX6577 SOT Temperature Sensors with Period/Frequency Output
Absolute Maximum Ratings
Terminal Voltage (with respect to GND) Operating Temperature Range...-40°C to +125°C VDD...-0.3V to +6V Storage Temperature Range..-65°C to +150°C TS1, TS0, OUT...-0.3V to (VDD + 0.3V) Lead Temperature (soldering, 10sec)...+300°C Input/Output Current, All Pins..±20mA Continuous Power Dissipation (TA = +70°C) 6-pin SOT23 (derate 7.10mW/°C above +70°C)..571mW 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.
Electrical Characteristics
(VDD = +2.7V to +5.5V, TA = -40°C to +125°C, unless otherwise noted. Typical values are specified at TA = +25°C and VDD = +5V, unless otherwise noted.)
