DG412FDY

Product Summary

The DG412FDY is quad, single-pole/single-throw (SPST), fault-protected analog switches. It is pin compatible with the industry-standard nonprotected DG412FDY. This new switch feature fault-protected inputs and Rail-to-Rail signalhandling 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 DG412FDY has four normally open (NO) switches. These CMOS switches operate with dual power supplies ranging 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 compatibility when using ±15V or a single +12V supply. For supply voltages of ±5V, +5V, and +3V, refer to the MAX4712 data sheet.
