Therefore, all switches must be turned off by putting
the strobe high and data-in-low, and then address-
ing all switches in succession.

DESCRIPTION
The M22100 combines a 4 x 4 array of crosspoints
(transmission gates) with a 4-line-to-16-line decoder
and 16 latch circuits. Any one of the sixteen trans-
mission gates (crosspoints) can be selected by ap-
plying the appropriate four line address. The
selected transmission gate can be turned on or off
by applying a logical one or zero, respectively, to the
data input and strobing the strobe input to a logical
one. Any number of the transmission gates can be
ON simultaneously.

PIN CONNECTIONS
When the required operating power is applied to the
22100, the states of the 16 switches are indetermi-
nate.
