I am simulating a digital circuit and I need to use a CMOS inverter 4009. There are three of them with different postfixes:

  1. 4009BCL
  2. 4009BCP
  3. 4009BD

What are the differences between BCL and BCP and BD?

    \$\begingroup\$ Are they DIFFERENT SIMULATIONS? Or do they all use the same simulation. Seems likely they are just package variants. \$\endgroup\$ Commented Jun 6, 2016 at 5:39
  • \$\begingroup\$ Three types has been offered in the same simulator (Multisim) for each CMOS 4000 series IC. yes I think you are right, it just about their package cases. The model specifications in the simulator are all the same for all the three. \$\endgroup\$ Commented Jun 6, 2016 at 5:41

BCL and BCP and BD are just referring to casing. So all three are the same.
