CD22M3494
16 x 8 x 1 BiMOS-E Crosspoint Switch
The Intersil CD22M3494 is an array of 128 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
EE
. Each of the 128
switches may be addressed via the ADDRESS input to the 7
to 128 line decoder. The state of the addressed switch is
established by the signal to the DATA input. A low or 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.
CS allows crosspoint array to be cascaded for matrix expansion.
