Description
The Mitel MT8809 is fabricated in MITEL鈥檚 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. Chip Select (CS) allows the
crosspoint array to be cascaded for matrix
expansion.
