Description

The Mitel MT093 is fabricated in MITEL’s ISO-CMOS
technology providing low power dissipation and high
reliability. The device contains a 8×12 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 input
bits. The selected switch can be turned on or off by
applying a logical one or zero to the DATA input.

Pin Description

Pin #* Name Description

1Y3Y3 Analog (Input/Output): this is connected to the Y3 column of the switch array.
2AY2Y2 Add ress Lin e (Inp ut).

3 RESET Master RESET (Input): this is used to turn off all switches. Active High.
4,5 AX3,AX0 X3 and X0 Address Lines (Inputs).
6,7 NC No Connection.

8-13 X6-X11 X6-X11 Analog (Inputs/Outputs): these are connected to the X6-X11 rows of the switch

array.
