Data Sheet January 1997 File Number
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
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.
