PALCE16V8Z-25JI

The PALCE16V8Z-25JI is a type of advanced PAL device built with low-power, high-speed, electrically erasable CMOS technology. It is functionally compatible with all 20-pin GAL devices. The macrocells offer a universal device archit ecture. The PALCE16V8Z-25JI offers zero standby power and high speed. At 30-A maximum standby current, the PALCE16V8Z-25JI accepts battery-powered operation for an extended period.Different levels of combinatorial logic can always be reduced to sum-of-products form to take advantage of the very wide input gates available in PAL devices. The equations are programmed into the device through floating-gate cells in the AND logic array that can be erased electrically.

Features of the PALCE16V8Z-25JI are:(1)pin and function compatible with all 20-pin PAL devices;(2)electrically erasa ble CMOS technology provides reconfigurable logic and full testability;(3)high-speed CMOS technology:5-ns propaga tion delay for "-5" version;7.5-ns propagation delay for "-7" version;(4)direct plug-in replacement for the PAL16 R8 series;(5)outputs programmable as registered or combinatorial in any combination;(6)peripheral Component Int erconnect (PCI) compliant;(7)programmable output polarity;(8)programmable enable/disable control.etc.
