APPLICATION INFORMATION (continued)
Stringent ESD testing is performed by TI, based on various conditions and procedures. Please contact TI for a
reliability report that documents test setup, methodology, and results.
The HBM of ESD testing is shown in Figure 5. Figure 6 shows the current waveform that is generated during a
discharge into a low impedance. The model consists of a 100-pF capacitor, charged to the ESD voltage of
concern, and subsequently discharged into the device under test (DUT) through a 1.5-k
resistor.

Figure 6. Typical HBM Current Waveform
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.
