Functional Description
The MT8809 is an analog switch matrix with an array
size of 8 x 8. The switch array is arranged such that
there are 8 columns by 8 rows. The columns are
referred to as the Y inputs/outputs and the rows are
the X inputs/outputs. The crosspoint analog switch
array will interconnect any X I/O with any Y I/O when
turned on and provide a high degree of isolation
when turned off. The control memory consists of a 64
bit write only RAM in which the bits are selected by
the address inputs (AY0-AY2, AX0-AX2). Data is
presented to the memory on the DATA input. Data is
asynchronously written into memory whenever both
the CS (Chip Select) and STROBE inputs are low
and are latched on the rising 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 inputs/outputs can be
interconnected by establishing appropriate patterns
in the control memory. A logical “0” on the RESET
input will asynchronously return all
locations to logical “0” turning off all crosspoint
switches regardless of whether CS is high or low.

Address Decode
The six address inputs along with the STROBE and
CS (Chip Select) 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
high and CS must go low while the address and data
are set up. Then the STROBE input is set low and
then high causing the data to be latched. The data
can be changed while STROBE is low, however, the
corresponding switch will turn on and off in
accordance with the DATA input. DATA must be
stable on the rising edge of STROBE in order for
correct data to be written to the latch.
