Description
The Zarlink MT8812 is fabricated in Zarlink’s ISO-
CMOS technology providing low power dissipation
and high reliability. The device contains a 8 x12 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 input bits. The selected switch can
be turned on or off by applying a logical one or zero
to the DATA input.
