Table 5: DC Electrical Specifications
Unless otherwise stated, VDD = 3.3V ± 10%, no load on any output, and ambient temperature range TA = 0°C to 70°C. Parameters denoted with an asterisk ( * ) represent nominal characterization
data and are not production tested to any specific limits. Where given, MIN and MAX characterization data are
± 3σfrom typical. Negative currents indicate current flows out of the device.
