Electrical Characteristics Notes
Note 1 Absolute Maximum Ratings indicate limits beyond which damage to the device may occur Operating Ratings indicate conditions for which the device is
intended to be functional but do not guarantee specific performance limits For guaranteed specifications and test conditions see the Electrical Characteristics
Note 2 Human body model 100 pF discharge through a 1 5 kX resistor All pins except pins 8 and 13 which are protected to 1000V and pins 1 2 18 and 19 which
are protected to 500V
Note 3 The maximum power dissipation is a function of TJMax iJA and TA and is limited by thermal shutdown The maximum allowable power dissipation at any
ambient temperature is PD e (TJMax b TA) iJA If this dissipation is exceeded the die temperature will rise above 150 C and the device will eventually go into
thermal shutdown For the LMD18400 the junction-to-ambient thermal resistance iJA is 60 C W With sufficient heatsinking the maximum continuous power
dissipation for the package will be IDCMax2 c RON(Max) c 4 switches (1A2 c 1 3X c 4 e 5 2W)
Note 4 Typical values are at TJ e a25 C and represent the most likely parametric norm
Note 5 All limits are 100% production tested at a25 C Limits at temperature extremes are guaranteed through correlation and accepted Statistical Quality
Control (SQC) methods
Note 6 Pulse Testing techniques used Pulse width is k 5 ms with a duty cycle k 1 %
