Figure 6. Typical HBM Current Waveform

Machine Model (MM)

The MM ESD test applies to all pins using a 200-pF capacitor with no discharge resistance. The purpose of the

MM test is to simulate possible ESD conditions that can occur during the handling and assembly processes of

manufacturing. In this case, ESD protection is required for all pins, not just RS-232 pins. However, after PC

board assembly, the MM test no longer is as pertinent to the RS-232 pins.
