SWITCHING CHARACTERISTICS—MAX3062E

, unless otherwise noted. Typical values are at V
CC
= +5V and T
A
= +25°C.) (Notes 1, 2)
Note 1: Overtemperature limits are guaranteed by design and are not production tested. Devices are tested at T
A
= +25°C.
Note 2: All currents into the device are positive; all currents out of the device are negative. All voltages are referred to device
ground, unless otherwise noted.
Note 3: ΔV
OD
and ΔV
OC
are the changes in V
OD
and V
OC
, respectively, when the DI input changes state.
Note 4: This input current level is for the hot-swap enable (DE, RE) inputs and is present until the first transition only. After the first
transition, the input reverts to a standard high-impedance CMOS input with input current I
IN1
. For the first 10µs, the input
current can be as high as 1mA. During this period the input is disabled.
Note 5: Maximum current level applies to peak current just prior to foldback-current limiting; minimum current level applies during
current limiting.
Note 6: The device is put into shutdown by bringing RE high and DE low. If the enable inputs are in this state for less than 50ns, the
device is guaranteed not to enter shutdown. If the enable inputs are in this state for at least 600ns, the device is guaranteed
to have entered shutdown.
