What this PAL device is and where it fits
The Microchip PALCE20V8H-25E4/BLA is an electrically erasable PAL device in a 24-CDIP ceramic package. It provides 8 macrocells with a propagation delay of 25 ns.
25 ns speed — timing margin for the bus
The 25 ns propagation delay sets the maximum system clock rate this PAL can support in a registered output path.
