ATF1504AS(L)
The ATF1504AS also supports the growing need in the industry to support the new
Peripheral Component Interconnect (PCI) interface standard in PCI-based designs and
specifications. The PCI interface calls for high current drivers, which are much larger
than the traditional TTL drivers. In general, PLDs and FPGAs parallel outputs to support
the high current load required by the PCI interface. The ATF1504AS allows this without
contributing to system noise while delivering low output-to-output skew. Having a pro-
grammable high drive option is also possible without increasing output delay or pin
capacitance. The PCI electrical characteristics appear on the next page.
