Description
The Zarlink MT8814 is fabricated in Zarlink’s ISO-
CMOS technology providing low power dissipation and
high reliability. The device contains a 8 x 12 array of
crosspoint switches along with a 7 to 96 line decoder
and latch circuits. Any one of the 96 switches can be
addressed by selecting the appropriate seven address
bits. The selected switch can be turned on or off by
applying a logical one or zero to the DATA input. V
SS
is
the ground reference of the digital inputs. The range of
the analog signal is from V
DD
to V
EE
. Chip Select (CS)
allows the crosspoint array to be cascaded for matrix
expansion.
