X Address Lines. These pins select one of the 16 rows of switches. See
the Truth Table for the valid addresses.
Y Address Lines. These pins select one of the 8 columns of switches. See
the Truth Table for the valid addresses.
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.
CHIP SELECT. Device is selected when CS is at a high level, allows the
crosspoint array to be cascaded for matrix expansion.
