CD22M3494SQZ

The Intersil CD22M3494 is an array of 128 analog switchescapable of handling signals from DC to video. Because ofthe switch structure, input signals may swing through thetotal supply voltage range, VDD to VEE. Each of the 128switches may be addressed via the ADDRESS input to the 7to 128 line decoder. The state of the addressed switch isestablished by the signal to the DATA input. A low or zeroinput will open the switch, while a high logic level or a onewill result in closure of the addressed switch when theSTROBE input goes high from its normally low state. Anynumber or combination of connections may be active at onetime. Each connection, however, must be made or brokenindividually in the manner previously described. All switchesmay be reset by taking the RESET input from a zero state toa one state and then returning it to its normal low state.
