Posted on Feb 5, 2014

Note that the function diagram for either the 5443 and 5444 are identical, assuming a 16-pin dual In-line package. The difference resided in the internal connections as shown in the functional schematic and how the inputs are decoded. That is, the pin-out and block diagram is identical, but the internal connections show the difference. Editor note; It is doubtful that an
