DG405DY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405DY+ is a dual, high-speed analog switch featuring two double-pole/single-throw (DPST) channels in a 16-pin Narrow SO package. It operates from single +10V to +30V or bipolar ±4.5V to ±20V supplies with a maximum power consumption of 35µW. The device guarantees low on-resistance matching between switches (2Ω max) and flatness over the signal range (3Ω max). Typical on-resistance is 20Ω, with a maximum of 45Ω for the C/D temperature grades. Switching times are 150ns max for turn-on and 100ns max for turn-off. It supports rail-to-rail signal handling and maintains TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the specific part number suffix matches the required operating temperature range before procurement. The 'DY' suffix indicates a -40°C to +85°C range, while other suffixes may differ. Confirm RoHS compliance status as indicated by the '+' symbol. Ensure the narrow SOIC package dimensions align with the target PCB footprint requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual DPST switching is required with tight on-resistance matching specifications. Consider the 150ns turn-on time for speed-sensitive applications. Verify that the analog signal range fits within the specified supply voltage limits. Check if the 16-pin Narrow SO package is suitable for the assembly process compared to DIP alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG401/DG403/DG405 family of improved, dual, high-speed analog switches. It shares the same pinout and general electrical characteristics as the DG401 and DG403 but differs in internal configuration. The DG405 specifically provides two DPST switches, whereas the DG401 offers two SPST switches and the DG403 provides dual SPDT functionality.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include DG405DJ and DG405CY. These variants share the same functional specifications but differ in package type and operating temperature range. Verify that the replacement package matches the physical constraints of the design.
