DESCRIPTION
The PALCE16V8 is a universal PAL device. It has eight independently configurable macrocells (MCo●● MC7). The macrocells can be configured as registered output, combinatorial output, combinatorial 1/0 or dedicated input. The programming matrix implements a programmable AND logic array, which drives a fixed OR logic array. Buffers for device inputs have co
