DG412DY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412DY is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation, housed in a 16-lead SOIC-Narrow package. It integrates four independent single-pole single-throw (SPST) switches with TTL and CMOS compatible digital inputs. The device supports single supplies from +5V to +44V or dual supplies of ±5V to ±20V. 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 operates within a temperature range of -40°C to +85°C and features low power consumption.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as the DG412 part number has been produced by multiple vendors including Analog Devices/Maxim Integrated and Vishay/Siliconix. Confirm that the specific DG412DY suffix corresponds to the intended supplier's pinout and electrical specifications before integration into the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a drop-in replacement for DG211/DG212 series devices is required with lower on-resistance and faster switching speeds. Ensure the system voltage requirements align with the 44V maximum rating and verify that the logic polarity matches the application needs, as it differs from the complementary DG411.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG412 belongs to the DG411 series family of monolithic quad SPST CMOS analog switches. These devices serve as direct upgrades to older DG211 and DG212 technologies, offering enhanced speed and lower resistance while maintaining compatibility with standard digital logic families.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411DYZ-T serves as a logical alternative where inverted logic control is preferred. Other manufacturers such as Analog Devices and Vishay produce equivalent parts under the same base model number; verify datasheet specifics for cross-supplier substitution.
