Description
The Mitel MT8806 is fabricated in MITEL’s ISOCMOS technology providing low power dissipation
and high reliability. The device contains a 8 x 4 array
of crosspoint switches along with a 5 to 32 line
decoder and latch circuits. Any one of the 32
switches can be addressed by selecting the
appropriate five address bits. The selected switch
can be turned on or off by applying a logical one or
zero to the DATA input. V
of the digital inputs. The range of the analog
signal is from V
to VEE. Chip Select (CS) allows
DD
the crosspoint array to be cascaded for matrix
expansion.

Pin Description
Pin #* Name Description
1-3 Y2-Y0 Y2-Y0 Anal og (Inputs/ Ou tputs): these are connected to the Y2-Y0 columns of the
switch array.
4DATADATA (Input): a logic high input will turn on the selected switch and a logic low will turn off
the selected switch. Active High.
5X0X0 Analog (Input/Output): this is connected to the X0 row of the switch array.
6AX0X0 Address Li n e (Input).
7X1X1 Analog (Input/Output): this is connected to the X1 row of the switch array.
8AX1X1 Address Li n e (Input).
9X2X2 Analog (Input/Output): this is connected to the X2 row of the switch array.
10 CS Chip Select (Input): this is used to select the device. Active High.
