ABSOLUTE MAXIMUM RATINGS
CM8500A
3A BUS TERMINATOR
Absolute maximum ratings are those values beyond which the
device could be permanently damaged.
PVDD/VCC/VCCQ ......................................â¦.......-0.3V to 6.0V
Voltage on Any Other Pin â¦â¦â¦... GND â 0.3V to VCC + 0.3V
Output RMS Current, Source or Sink .....â¦â¦â¦â¦........â¦...3.0A
Junction Temperature ...â¦â¦â¦â¦â¦â¦â¦â¦ â¦â¦â¦â¦150°C
Storage Temperature â¦â¦................â¦â¦. -65°C to 125°C
Lead Temperature (Soldering, 5 sec)â¦â¦â¦â¦â¦â¦.. 260°C
Thermal Resistanceï¨(θJA )â¦.. â¦â¦â¦â¦â¦â¦â¦.. .40°C/W
OPERATING CONDITIONS
Temperature Range ............................. -40°C to 85°C
PVDD Operating Range .........................2.0V to 5.0V
ELECTRICAL CHARACTERISTICS (Unless otherwise stated, these specifications apply TA=25°C;
VCC=+3.3V and PVDD=+3.3V) maximum ratings are stress ratings only and functional device operation is not implied.(Note 1)
