Stresses above those listed under Absolute Maximum Ratings
Parameter Rating
may cause permanent damage to the device. This is a stress VDD to GND −0.3 V to +7 V rating only; functional operation of the device at these or any DIN Input Voltage to GND −0.3 V to VDD + 0.3 V other conditions above those indicated in the operational DOUT Output Voltage to GND −0.3 V to VDD + 0.3 V section of this specification is not implied. Exposure to absolute SCLK Input Voltage to GND −0.3 V to VDD + 0.3 V maximum rating conditions for extended periods may affect CS Input Voltage to GND −0.3 V to VDD + 0.3 V device reliability. CT and INT Output Voltage to GND −0.3 V to VDD + 0.3 V ESD Rating (Human Body Model) 2.0 kV
