DG413FDY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG413FDY+ is a quad, single-pole/single-throw (SPST) CMOS analog switch featuring fault protection and rail-to-rail signal handling. It contains two normally closed (NC) and two normally open (NO) switches within a 16-pin SOIC package. The device operates on dual supplies from ±4.5V to ±20V or a single supply between +9V and +36V. Key electrical parameters include a maximum on-resistance of 35Ω at +25°C, with a maximum channel-to-channel match of 1.5Ω. Turn-on time is typically 70ns and turn-off time is typically 55ns under ±15V dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs and terminals withstand overvoltage faults up to ±36V with power applied and ±40V with power off.
• Rail-to-Rail signal-handling capability allows signals to pass through the switch even when slightly beyond the supply rails.
• TTL and CMOS compatible logic inputs ensure compatibility across various digital control standards.
• Pin-compatible with industry-standard non-protected DG411/DG412/DG413 devices for direct replacement.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'DY' corresponds to the 16-pin Small Outline (SO) package configuration. Confirm that the '+' suffix indicates RoHS compliance status as defined by the manufacturer's current documentation. Ensure the component meets the required operating temperature range of -40°C to +85°C for the intended application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required for analog signal paths exceeding standard supply voltages. The mixed NC/NO configuration in the DG413F variant supports independent control of turn-on and turn-off times for SPDT configurations. Verify that the 35Ω maximum on-resistance and low charge injection meet the signal integrity requirements of the target circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG413F belongs to the redesigned DG411F/DG412F/DG413F series, which serves as an upgrade to the popular DG211 and DG212 series devices. These switches utilize a high-voltage silicon-gate process to prevent latch-up and offer lower on-resistance matching and faster switching speeds compared to their predecessors.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG413F handle break-before-make operations?

The DG413F features two NC and two NO switches with different logic polarities. This allows independent control of turn-on and turn-off times, enabling break-before-make or make-before-break operation with minimal external logic.

What is the fault response time during an overvoltage event?

The typical fault output turn-off delay is 20ns when the input voltage exceeds the supply rails by approximately 50mV. Fault recovery time is typically 1µs for positive faults and 0.5µs for negative faults.

Can the DG413FDY+ operate with asymmetrical power supplies?

Yes, the V+ and V- supplies need not be symmetrical, provided their difference does not exceed the absolute maximum rating of 44V.
