The Zarlink MT8809 is fabricated in Zarlink’s ISOCMOS 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. Chip
Select (CS) allows the crosspoint array to be cascaded
for matrix expansion.
