7.2.5 Designing for Improved ESD Performance
The TLC555 internal HBM and CDM protection allows for safe assembly in ESD-controlled environments. In applications that expose the pins of the TLC555 to ESD, additional protection is highly recommended. The following test board schematic has bypass capacitors, current-limiting resistors, and voltage-clamping TVS diodes to provide additional protection for commonly exposed pins (Reset, Trig, and Output) against ESD.
Figure 7-10 ESD
Test SchematicThe following table gives the ESD protection levels recorded for different supply voltages and external components populated. Using only passive components to protect the TLC555 with a single 15?V supply is not recommended because the higher voltage allows for an unacceptable amount of current to flow through the device.
