The DG411F/DG412F/DG413F are quad, single-pole/sin- gle-throw (SPST), fault-protected analog switches. They are pin compatible with the industry-standard nonpro- tected DG411/DG412/DG413. These new switches fea- ture fault-protected inputs and Rail-to-Rail signal- handling capability. All terminals are protected from overvoltage faults up to ±36V with power on and up to ±40V with power off. During a fault condition, the COM, NO, or NC terminal becomes an open circuit and only microamperes of leakage current flow from the source. On-resistance is 35Ω (max) and is matched between switches to 1.5Ω (max) at +25°C. The DG411F has four normally closed (NC) switches. The DG412F has four normally open (NO) switches. The DG413F has two NC and two NO switches. These CMOS switches operate with dual power supplies rang- ing from ±4.5V to ±20V or a single supply between +9V and +36V. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic com- patibility when using ±15V or a single +12V supply. For supply voltages of ±5V, +5V, and +3V, refer to the MAX4711/MAX4712/MAX4713 data sheet.
The DG411F, DG412F, and DG413F are quad, single‑pole/single‑throw analog switches that feature fault‑protected inputs and rail‑to‑rail signal handling. They are pin‑compatible with the standard DG411/DG412/DG413 devices and can replace them without redesign.
These switches operate from dual supplies of ±4.5 V to ±20 V or a single supply of +9 V to +36 V, provide TTL‑ and CMOS‑compatible logic thresholds, and include built‑in over‑voltage protection up to ±36 V (power on) or ±40 V (power off). Typical applications include communication systems, signal routing, test equipment, and industrial control.
