GENERAL DESCRIPTION
The PALCE16V8 is an 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 provide a universal device architecture. The PALCE16V8 will directly replace the PAL16R8, with the exception of the PAL16C1.
The PALCE16V8Z provides zero standby power and high speed. At 30-µA maximum standby current, the PALCE16V8Z allows battery-powered operation for an extended period.
