4.1Absolute Maximum Ratings

Table 1. Absolute Maximum Ratingsa

Symbol	Parameter	Min	Max	Unit

VDD	DC supply voltage	-0.3	7	V
VIN	Input voltage	-1	VDD + 0.3	V
IIN	DC input pin current	-10	10	mA
TSTG	Storage	-40	125	° C
TSTG	temperature	-40	125	° C

a.Maximum ratings are referenced to ground (VSS). Permanent device damage is likely to occur if the ratings in this table are exceeded. These values should not be used as the limits for normal device operations.
