ABSOLUTE MAXIMUM RATINGS
CM8501/A
1.5A BUS TERMINATOR
Absolute maximum ratings are those values beyond which the
device could be permanently damaged.
PVDD/VCCA/VCCQ ......................................â¦.......-0.3V to 4.0V
Voltage on Any Other Pin â¦â¦â¦â¦... GND â 0.3V to VCC + 0.3V
Output RMS Current, Source or Sink .....â¦â¦â¦â¦........â¦...1.5A
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¦.. 300°C
16-Pin Package Thermal Resistanceï¨(θJA )â¦.. .. .40°C/W
8-Pin Package Thermal Resistanceï¨(θJA )â¦.â¦.. .50°C/W
OPERATING CONDITIONS
Temperature Range ............................. -40°C to 85°C
PVDD Operating Range .........................2.0V to 4.0V
ELECTRICAL CHARACTERISTICS (Unless otherwise stated, these specifications apply TA=25°C;
VCCA=+3.3V and PVDD=+3.3V) maximum ratings are stress ratings only and functional device operation is not implied.
