*1: On account of parts procurement situation , the TC40H138FN was used as a substituti o n of the
TC74HC138F for some of CE-201 M and CE-202M in earlier productions . When the TC4 0 H -
13 8 FN on is in failure, either the TC40H138FN or TC74HC138F can be used as a replacement.
But when the TC74HC138F is in use, it has to be replaced by the TC7 4 HC138F, not t h e TC -
40H138FN which may impede proper operation due to variation in access ti m e b y the RAM chip
