CD22M3493
12 x 8 x 1 BiMOS-E Crosspoint Switch
The Intersil CD22M3493 is an array of 96 analog switches
capable of handling signals from DC to video. Because of
the switch structure, input signals may swing through the
total supply voltage range, V
DD
to V
SS
. Each of the 96
switches may be addressed via the ADDRESS input to the
7 to 96 line decoder. The state of the addressed switch is
established by the signal to the DATA input. A low or logic
zero input will open the switch, while a high logic level or a
one will result in closure of the addressed switch when the
STROBE input goes high from its normally low state. Any
number or combination of connections may be active at
one time. Each connection, however, must be made or
broken individually in the manner previously described. All
switches may be reset by taking the RESET input from a
zero state to a one state and then returning it to its normal
low state.

To make a connection (close switch) between any two points, specify an ``X'' address, a ``Y'' address, set ``DATA'' high, and switch
``Strobe'' from low to high. To break a connection, follow this same procedure with ``DATA'' low.:

DATA Input determines the state of the addressed switch. A high or one will close the
switch. A low or zero will open the switch.
STROBE

STROBE Input enables the action defined by the DATA and ADDRESS Inputs. A low or
zero results in no action. The ADDRESS Input must be stable before the STROBE Input
goes to the active high level. The DATA Input must be stable on the failing edge of the
STROBE.
