Description
The Mitel MT8816 is fabricated in MITEL’s ISO­CMOS technology providing low power dissipation and high reliability. The device contains a 8 x 16 array of crosspoint switches along with a 7 to 128 line decoder and latch circuits. Any one of the 128 switches can be addressed by selecting the appropriate seven address bits. The selected switch can be turned on or off by applying a logical one or zero to the DATA in p ut . V of the digital inputs. The range of the analog signal is from V
to VEE. Chip Select (CS) allows the
DD
crosspoint array to be cascaded for matrix expansion.
