NOTES
(1)
The human body model is defined as a 100pF capacitor which is discharged through a 1.5 kΩ resistor into
each pin according to JESD-22-114.
(2)
Device mounted without heatsink. No air flow.
(3)
MIN and MAX limits are 100% production tested at 25°C. Limits over the operating temperature range are
guaranteed through correlation using Statistical Quality Control (SQC) methods.
(4)
Typical numbers are valid at 25°C ambient temperature and represent statistically the utmost probability
assuming the Gaussian distribution.
(5)
MTBF: Mean time before failure

ELECTRICAL SPECIFICATIONS
MIN and MAX values are valid for recommended ambient temperature range of -40°C to 85°C. Typical values
represent statistically the utmost probability at following conditions: Vin = 6V (3.3V version), Vin = 7V (5V versi-
on) to 28V at ambient temperature of 25°C (unless otherwise noted)
