DEFAULT CONDITIONS
Table A-5 lists the values of the signals for the 87C196LA and 87C196LB during various oper-
ating conditions. Table A-6 lists the same information for the 83C196LD. Table A-4 defines the
symbols used to represent the pin status. Refer to the DC characteristics table in the datasheet for
actual specifications for V
