Additional Details
The PALC22V10L-25WC typically comes in a plastic package. Detailed specifications include propagation delay, power dissipation, input/output voltage levels, and operating temperature range. The internal architecture consists of a programmable AND array driving a fixed OR array with output macrocells. These macrocells allow configuration of each output as either registered or combinatorial, and active high or active low. Programming is performed using specialized PAL programmers, and the device is often electrically erasable, enabling reprogramming and design iteration.
