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 15 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 is60 CW With sufficient heatsinking the maximum continuous power

dissipation for the package will be IDCMax2 c RON(Max) c 4 switches (1A2 c 13X c 4 e 52W)

Note 4

Typical values are at TJ ea25 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%
