LTC1380/LTC1393
ELECTRICAL CHARACTERISTICS
(Notes 2, 4)
The
G
denotes specifications which apply over the full operating
temperature range.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
All current into device pins is positive; all current out of device
pins is negative. All voltages are referenced to ground unless otherwise
specified. All typicals are given for T
A
= 25
°
C, V
CC
= 5V (for both LTC1380
and LTC1393) and V
EE
= –5V (LTC1380).
Note 3:
These typical parameters are based on bench measurements and
are not production tested.
Note 4:
Both SCL and SDA assume an external 15k pull-up resistor to a
typical SMBus host power supply V
DD
of 5V.
Note 5:
Typical curves with V
EE
= –5V apply to the LTC1380. Curves with
V
EE
= 0V apply to both the LTC1380 and the LTC1393.
Note 6:
These parameters are guaranteed by design and are not tested in
production.
