ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are those values beyond which
the device could be permanently damaged. Absolute
maximum ratings are stress ratings only and functional
device operation is not implied.
VCC ............................................................................... –0.3V to 6V
Input Pin Voltages ............................. –0.3V to VCC +0.3V
LED Output Current ............................................. 120mA
ML4632
PEAK DC Output Current ..................................... 120mA
Storage Temperature .............................. –65°C to +150°C
Lead Temperature (Soldering 10 sec.) ..................... 260°C
ELECTRICAL CHARACTERISTICS
Over the recommended operating conditions of TA = 0°C to 70°C, VCC = 5V ±5%, unless otherwise specified. (Note 1)
