DG612DY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG612DY-E3 is a high-speed, low-glitch quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It utilizes a proprietary D/CMOS process combining lateral DMOS switching FETs with low-power CMOS control logic to achieve fast switching and minimal charge injection. The device operates on dual supplies ranging from -10 V to +21 V for V+ and -10 V to 0 V for V-, with a maximum analog signal range of 16 V peak-to-peak. Key electrical parameters include a typical turn-on time of 12 ns, an on-resistance of 18 Ω, and a bandwidth of 500 MHz. It features 5 V CMOS logic compatibility, low quiescent power consumption of 1.2 nW, and is housed in a 16-pin Narrow SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead-free status. Ensure that the logic level requirements match the system design, as the DG612 responds to opposite logic levels compared to the DG611. Confirm supply voltage ranges align with the recommended operating conditions specified in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG612DY-E3 when low charge injection and high speed are critical for maintaining signal integrity in precision analog applications. Consider the opposite logic response relative to the DG611 if complementary switching actions are required within the same system. Evaluate the thermal derating requirements for the SOIC package based on the expected power dissipation in the target environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG612 is part of the DG611/DG612/DG613 family of high-speed analog switches. While the DG611 and DG612 both feature four SPST switches, they differ in their control logic polarity. The DG613 offers a mixed configuration of normally open and normally closed switches. This family is designed for applications requiring fast switching with minimal glitch energy.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG611DY-E3 serves as a functional substitute with identical electrical characteristics but inverted control logic. Designers must verify that the logic inversion does not conflict with existing control signals before swapping these components.
