ABSOLUTE MAXIMUM RATINGS(1)
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas
Instrumentsrecommendsthatallintegratedcircuitsbehandled
with appropriate precautions. Failure to observe proper han-
dling and installation procedures can cause damage.
+VDD to GND ........................................................................ –0.3V to +6V
Digital Input Voltage to GND ................................. –0.3V to +VDD + 0.3V
Operating Temperature Range ...................................... –40°C to +105°C
Storage Temperature Range .........................................–65°C to +150°C
Junction Temperature (TJ max) .................................................... +150°C
TSSOP Package
Power Dissipation .................................................... (TJ max – TA)/θJA
θJA Thermal Impedance ........................................................ 240°C/W
Lead Temperature, Soldering
ESD damage can range from subtle performance degradation
tocompletedevicefailure. Precisionintegratedcircuitsmaybe
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
Vapor Phase (60s) ............................................................ +215°C
Infrared (15s) ..................................................................... +220°C
NOTE: (1) Stresses above those listed under Absolute Maximum Ratings may
cause permanent damage to the device. Exposure to absolute maximum
conditions for extended periods may affect device reliability.
