Thin Film On Silicon 2DTG Super Terminator/Filter with Integrated ESD Array
General Information
The Model 2DTG Series IEEE 1284 Terminator/Filter is a multi-functional single device interface for IEEE EPP/ECP designs. In addition to termination and filtering, the Model 2DTG offers 8 KV contact discharge and 15 KV air discharge (per Human Body model) of ESD protection and is specifically designed to meet the requirements of ESD system specification IEC 61000-4-2. This highly integrated product is well-suited for use in space-constrained applications such as PC notebooks and motherboards, NT servers, engineering workstations, and portable battery powered devices. It is also useful in peripheral products which are designed to communicate through the EPP/ECP parallel port such as inkjet and laser printers, portable/removable drives, scanners, digital cameras, tape back-ups, LANs and other communication interfaces.

* Note: IEC 61000-4-2 ESD test performance is measured at the systems level and system designs, enclosure shielding and other conventional ESD control measures usually influence the results of these tests. Testing on the component level serves as an indicator that the system passes a specific compliance step, but does not ensure that the system passes at that level. The Model 2DTG device, therefore, can support successful implementation of the IEC 61000-4-2 system level ESD standard.
