General Information
The Model 2DTF 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
2DTF 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 2DTF device, therefore, can support successful implementation of the IEC 61000-4-2 system level ESD standard.
