Quad LIN 2.2A/SAE J2602 transceiver
8. Limiting values
[1] Equivalent to discharging a 150 pF capacitor through a 330 resistor.
[2] Equivalent to discharging a 100 pF capacitor through a 1.5 k resistor.
[3] Equivalent to discharging a 200 pF capacitor through a 10 resistor and a 0.75 H coil.
[4] Junction temperature in accordance with IEC 60747-1. An alternative definition is: T

, where R
th(j-a)
is a fixed value.
The rating for T

limits the allowable combinations of power dissipation (P) and ambient temperature (T
amb
).
9. Thermal characteristics
[1] According to JEDEC JESD51-2, JESD51-5 and JESD51-3 at natural convection on 1s board with thermal via array under the exposed
pad connected to the second copper layer.
[2] According to JEDEC JESD51-2, JESD51-5 and JESD51-7 at natural convection on 2s2p board. Board with two inner copper layers
(thickness: 35 m) and thermal via array under the exposed pad connected to the first inner copper layer.
Table 5. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are referenced to pin GND, unless
otherwise specified. Positive currents flow into the IC.
