Electrical characteristics
This chapter provides the electrical characteristics for SPEAr1340.
Please refer to AN3317, Application notes, PCB guidelines for SPEAr1340 for additional
details.
4.1
Absolute maximum ratings
SPEAr1340 contains devices to protect the inputs against damage due to high/low static
voltages. However, it is advisable to take normal precaution to avoid application of any
voltage higher/lower than the specified maximum/minimum rated voltages.
Caution:
Stresses above those listed in Table 39 and Table 40 may cause permanent damage to the
device. Exposure to maximum rating conditions for extended periods may affect device
reliability.
