Note 3:
These typical parameters are based on bench measurements and temperature range. are not production tested.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 4:
Both SCL and SDA assume an external 15k pull-up resistor to a of a device may be impaired. typical SMBus host power supply VDD of 5V.
Note 2:
All current into device pins is positive; all current out of device
Note 5:
Typical curves with VEE = – 5V apply to the LTC1380. Curves with pins is negative. All voltages are referenced to ground unless otherwise VEE = 0V apply to both the LTC1380 and the LTC1393. specified. All typicals are given for TA = 25°C, VCC = 5V (for both LTC1380
