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.
