Description
The Mitel MT8809 is fabricated in MITEL’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.
