ATF1502AS(L)
The ATF1502AS 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 ATF1502AS allows this without contributing to system noise while
delivering low output to output skew. Having a programmable high drive option is also possible
without increasing output delay or pin capacitance. The PCI electrical characteristics appear
on the next page.
