NOTE: 4. When X switch addresses are in these states, no change in

To make a connection (close switch) between any two points, specify an ‘‘X’’ address, a ‘‘Y’’ address, set ‘‘DATA’’ high, and switch
‘‘Strobe’’ from low to high. To break a connection, follow this same procedure with ‘‘DATA’’ low.:

DATA Input determines the state of the addressed switch. A high or one will close the
switch. A low or zero will open the switch.
STROBE Input enables the action defined by the DATA and ADDRESS Inputs. A low or
zero results in no action. The ADDRESS Input must be stable before the STROBE Input
goes to the active high level. The DATA Input must be stable on the failing edge of the
STROBE.
MASTER RESET. A high or one on this line opens all switches.
