DG411DYZ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411DYZ is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Renesas Electronics Corporation. It features four independent switches with TTL and CMOS compatible digital inputs, serving as a drop-in replacement for the DG211 and DG212 series. The device utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latch-up. Key electrical parameters include a maximum on-resistance of 35 ohms, a maximum turn-on time of 175 ns, and a maximum turn-off time of 145 ns. It supports single supply voltages from 5 V to 34 V or dual supplies from ±5 V to ±20 V, allowing control of signals up to 40 V peak-to-peak.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation as Renesas Electronics Corporation, noting historical Intersil origins. Confirm the package type is SOIC-Narrow-16 and check RoHS compliance status via official datasheets. Ensure the specific suffix matches the required tape-and-reel or tube packaging configuration for your assembly line.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low charge injection and fast switching speeds are critical for signal integrity. Compare against DG412 if inverted logic control is required instead of non-inverting. Verify that the 35-ohm on-resistance meets the voltage drop requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411 series belongs to a family of precision monolithic CMOS analog switches designed to replace older DG211/DG212 devices. The DG411 variant specifically uses non-inverting logic, distinguishing it from the DG412 which uses inverting logic. This series leverages advanced silicon-gate technology for improved performance metrics.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG411 differ from the DG412?

The DG411 and DG412 are electrically identical but differ in the polarity of their selection logic. The DG411 uses non-inverting logic, while the DG412 uses inverting logic.

What is the maximum power dissipation?

The maximum power dissipation is typically rated at 600 mW, depending on the thermal characteristics of the PCB and ambient temperature.
