National’s patent ESD protection and EMI reduction circuits are implemented on device
to address ESD/EMI problems.
2.22 INPUT PROTECTION
The COP8SAx7 input pins have internal circuitry for protection from ESD. The internal
circuitry is shown in Figure 2-31.
The input protection circuitry is implemented with the P_channel transistors. The
equivalent diode circuit is shown in Figure 2-32.
