3 / 12 page  3 LTC1380/LTC1393 ELECTRICAL CHARACTERISTICS (Notes 2, 4) The q 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 TA = 25°C, VCC = 5V (for both LTC1380 and LTC1393) and VEE = – 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 VDD of 5V. Note 5: Typical curves with VEE = – 5V apply to the LTC1380. Curves with VEE = 0V apply to both the LTC1380 and the LTC1393. Note 6: These parameters are guaranteed by design and are not tested in production.
