S F/F Q
R A
Sets ON device A when set
input (S) is ON, and resets OFF
device A when reset input (R) is
ON.

counter
U U/D Q
C
E A
While enable input (E) is ON,
counts up or down the number
of cycles the count input (C)
comes ON, depending on the
up/down select input (U).
Up when U is ON, down when U
is OFF.
