(VIN = +2.3V to +5.5V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VIN = +3.3V, TA = +25°C.) (Note 1)

Note 1: All parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.

Note 2: Latchoff current does not include the current flowing into FLAG.

Note 3: The on-time is defined as the time taken for the current through the switch to go from 0mA to 10mA. The off-time is defined

as the time taken for the current through the switch to go from 10mA to 0mA.

Note 4: Retry time is typically 15 times the blanking time.

(VIN = 3.3V, TA = +25°C, unless otherwise noted.)
