Description
The Mitel MT8816 is fabricated in MITEL’s ISO-
CMOS 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 input. V
SS
is the ground refer-ence
of the digital inputs. The range of the analog signal
is from V
DD
to V
EE
. Chip Select (CS) allows the
crosspoint array to be cascaded for matrix
expansion.
