Note:
Stresses greater than those listed under MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any
other conditions above those indicated in the operational sec-
tions of this specication is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Notes:
1. For Max. or Min. conditions, use appropriate value specied under Electrical Characteristics for the applicable device type.
2. Typical values are at V
CC
= 3.3V, T
A
= 25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Measured by the voltage drop between A and B pin at indicated current through the switch. On-Resistance is determined
by the lower of the voltages on the two (A,B) pins.
5. This parameter is determined by device characterization but is not production tested.
