Description
The Zarlink MT093 is fabricated in Zarlink's ISOCMOS technology providing low power dissipation and high reliability. The device contains a 8x12 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.

Functional Description
The MT093 is an analog switch matrix with an array size of 8 x 12. The switch array is arranged such that there are 8 columns by 12 rows. The columns are referred to as the Y input/output lines and the rows are the X input/output lines. The crosspoint analog switch array will interconnect any X line with any Y line when turned on and provide a high degree of isolation when turned off. The control memory consists of a 96 bit write only RAM in which the bits are selected by the address input lines (AY0-AY2, AX0-AX3). Data is presented to the memory on the DATA input line. Data is asynchronously written into memory whenever the STROBE input is high and is latched on the falling edge of STROBE. A logical "1" written into a memory cell turns the corresponding crosspoint switch on and a logical "0" turns the crosspoint off. Only the crosspoint switches corresponding to the addressed memory location are altered when data is written into memory. The remaining switches retain their previous states. Any combination of X and Y lines can be interconnected by establishing appropriate patterns in the control memory. A logical "1" on the RESET input line will asynchronously return all memory locations to logical "0" turning off all crosspoint switches.
Address Decode
The seven address lines along with the STROBE input are logically ANDed to form an enable signal for the resettable transparent latches. The DATA input is buffered and is used as the input to all latches. To write to a location, RESET must be low while the address and data lines are set up. Then the STROBE input is set high and then low causing the data to be latched. The data can be changed while STROBE is high, however, the corresponding switch will turn on and off in accordance with the data. Data must be stable on the falling edge of STROBE in order for correct data to be written to the latch.
