Additional Details

The PAL22V10D-7JC features 22 inputs and 10 outputs. The "-7" in the part number indicates a propagation delay of 7 nanoseconds. The device is typically programmed using a PAL programmer. Its output macrocells can be configured as either combinatorial or registered outputs. The programming is done using fusible links. The PAL device is packaged in a ceramic DIP (Dual In-line Package). It is widely used in older electronic designs. Cypress's PAL devices are known for their reliability and performance in various digital systems.
