Note 1: All devices are 100% tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 2: Supply current is measured when switch is on (i.e., SHDN = V
CC
, t > t
ON
).
Note 3: Supply voltage level where the device enters its power-down cycle.
Note 4: Turn-on time is measured from the time V
CC
= 3V and SHDN > V

specification is met.
Note 5: Switch turn-off time is measured from the time SHDN < V

until the off-isolation specification is met.
Note 6: See the Power-Supply Rejection Ratio section for test method.
