I am not sure what the individual letters mean, but collectively they mean 40 pin plastic DIP 0 degee's to + 70 degrees C. It will fit in a 40 pin
dip socket with 0.6" spacing.
Yes, PDIP is the right type. 40pins with 2.54mm (0.1") distance. CERDIP also useable, but the pinout mirrored. CPL after the type-number just the temperature.
