CD74HC40103: Need a Logic Diagram

James Suttles
Prodigy 40 points
Part Number: CD74HC40103
Other Parts Discussed in Thread: TINA-TI

I am trying to build a CD74HC40103 macro in TINA-TI.  Most of the datasheets usually contain a logic diagram that

I can work from.  However, on this particular part, there is not one.  I realize that this part is a combination D-type and

T-type flip-flop counter, with Master Reset, Terminal Enable, and both Synchronous and Asynchronous control inputs. 

(Kind of an unusual part).  I would like to know if a logic diagram is available for this part. 

Thank you very much for your help - James Suttles

    Hi James,

    I'm glad to hear someone other than me is working on making macro-type models for logic devices.

    I haven't gotten around to this device yet -- I'm afraid these Harris devices that TI acquired (CD74...) don't have any hidden documentation. We only have access to the same datasheet that you do.  I'll be working backwards to figure out what's in this device if/when I get around to building a model for it.

    Sorry I'm not more help.
