DG211CSE+T Quad SPST Normally Closed Analog Switch

DG211CSE+T is useful when a default connected state matters, such as fail-safe signal routing and power-up measurement paths. It’s a normally closed, quad SPST analog switch, so each channel is on until you drive the control input. DG211CSE+T supports continuous operation with supplies ranging from ±4.5 V to ±18 V. The datasheet also states break-before-make switching and notes a latchup-resistant construction when supplies are disconnected while input signals remain connected. Use DG211CSE+T to gate multiple sensor lines, isolate test points, or manage analog routing in instrumentation and process control without relays. Keep control signals clean and referenced to your logic domain to avoid unintended switching during transients. Request a quote for DG211CSE+T.
