Description
The Mitel MT8815 is fabricated in MITEL’s ISO-
CMOS technology providing low power dissipation
and high reliability. The device contains a 8 x 12
array of crosspoint switches along with a 7 to 96 line
decoder and latch circuits. Any one of the 96
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 reference
of the digital inputs. The range of the analog signal
is from V
DD
to V
EE
.
