Negative Analog Power Supply.
Internal Connection.
Positive Power Supply.
Digital Ground Reference.
X0-X3 I/O Address Select (inputs).
Y0-Y7 I/O Address Select (inputs).
No Connection.
DATA (input/output). When input, a logic high will close the selected switch and a logic
low will open the selected switch. When output, a logic high indicates a closed switch
and a logic low indicates an opened switch.
Chip Select (input). Active low.
34
R/W READ/WRITE Control (input). When high the DATA pin is an output (for reading from
second stage latch); when low the DATA pin is an input (for writing to first stage latch).
35 STROBE1 STROBE 1 (input). Modifies memory content of first stage latch as determined by the
addess and data lines, but does not change the switch array configuration of entire
switch array. Active low.
36 STROBE2 STROBE 2 (input). Transfers memory content of first stage latch to the second stage
latch and hence, changes the configuration of entire switch array. Active low.
37
MR MASTER RESET (input). Used to reset the first and second stage latches. Active low.
38
NC No Connection.
