Clock Modulator for LCD Panels
ABSOLUTE MAXIMUM RATINGS
Voltage Range on VCC Relative to GND .............-0.5V to +3.63V
Voltage Range on Any Pin Relative
to GND ................-0.5V to (VCC + 0.5V), not to exceed +3.63V
Operating Temperature Range .........................-40°C to +125°C
Continuous Power Dissipation (TA = +70°C)
TSSOP (derate 8.1mW/°C above +70°C) ..................646.7mW
Storage Temperature Range .............................-55°C to +125°C
Lead Temperature (soldering, 10s) .................................+300°C
Soldering Temperature (reflow) .......................................+260°C
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.
RECOMMENDED OPERATING CONDITIONS
(TA = -40°C to +125°C, unless otherwise noted.)
