Recommended Operating Conditions
The VSC8101 and VSC8102 can be powered by:
a) connecting VCC to +2V and VTT to GND, or
b) connecting VCC to GND and VTT to -2V.
Power Supply Voltage (VCC -VTT)........................................................................................................ 2.0V ± 5%
Operating Temperature Range(2) ........................................................................................................ 0° to +70°C
Notes:
(1) CAUTION: Stresses listed under “Absolute Maximum Ratings” may be applied to devices one at a time without causing pe
manent damage. Functionality at or above the values listed is not implied. Exposure to these values for extended periods
may affect device reliability.
(2) Lower limit is ambient temperature and upper limit is case temperature.
