Description
The Zarlink MT8808 is fabricated in Zarlink’s ISO-
CMOS technology providing low power dissipation
and high reliability. The device contains a 8 x 8 array
of crosspoint switches along with a 6 to 64 line
decoder and latch circuits. Any one of the 64
switches can be addressed by selecting the
appropriate six address bits. The selected switch can
be turned on or off by applying a logical one or zero
to the DATA input. V
