Bypassed with a 0.1 /C0109F Ceramic Capacitor.
- These 2 pins need to be connected together in −line on the PCB.
- This output can be connected to an external 0.1 /C0109F ceramic capacitor, resulting in an increased ESD withstand voltage rating.
- Standard IEC 61000 −4−2, CDISCHARGE = 150 pF, RDISCHARGE = 330 /C0087, 5V_SUPPLY and LV_SUPPLY within recommended operating
- Human Body Model per MIL−STD−883, Method 3015, CDISCHARGE = 100 pF, RDISCHARGE = 1.5 k/C0087, 5V_SUPPLY and LV_SUPPLY within
