电气特性
参数条件
Unless otherwise specified:
all voltages are referenced to VSS.
typical data are based on TA = 25 °C, VDD = 3.3 V (for the 1.8 V ≤ VDD ≤ 3.6 V voltage range).
绝对最大额定值
Exposure to maximum rating conditions for extended periods may affect
device reliability.
Input voltage on 5v tolerant pin：VSS-0.3~VDD+4V
Input voltage on any other pin:VSS-0.3~4V
