7.5 ns propagation delay — timing budget for legacy 5V buses
The Microchip ATF16V8C-7JC is an electrically-erasable programmable logic device (EE PLD) from the 16V8 series, delivering a 7.5 ns propagation delay from input to combinatorial output. This speed places it in the fast end of the 16V8 family, suitable for address decoding, state-machine sequencing, and bus-interface glue logic in 5V systems where the timing margin is tight.
8 macrocells — what the logic capacity means for your design
With 8 macrocells, each configurable as registered or combinatorial, this part handles small-scale logic consolidation — replacing a handful of 74-series gates or a single PAL. The 5V-only input voltage ties it to legacy 5V logic families; it will not interface directly with 3.3V or lower-voltage cores without level translation.
20-PLCC footprint — board-level fit and rework
The 20-PLCC (9x9 mm) package is a surface-mount footprint common in late-1990s through mid-2000s industrial and telecom designs. The J-lead form factor allows visual inspection of solder joints and is reworkable with standard hot-air tools.
Microchip lists the ATF16V8C-7JC as Obsolete.
