Parameter Rating
may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any VDD to GND –0.3 V to +7 V other conditions above those indicated in the operational DIN Input Voltage to GND –0.3 V to VDD + 0.3 V section of this specification is not implied. Exposure to absolute DOUT Voltage to GND –0.3 V to VDD + 0.3 V maximum rating conditions for extended periods may affect SCLK Input Voltage to GND –0.3 V to VDD + 0.3 V device reliability.

ESD CAUTION
1 Values relate to package being used on a standard 2-layer PCB. This gives a worst-case θJA and θJC. See Figure 4 for a plot of maximum power dissipation vs. ambient temperature (TA). 2 TA = ambient temperature. 3 Junction-to-case resistance is applicable to components featuring a preferential flow direction, for example, components mounted on a heat sink. Junction-to-ambient is more useful for air-cooled, PCB-mounted components. Rev.
