CD22M3494MQ

 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, VDD to VEE. 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.
