DG308ACJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG308ACJ+ is a quad, single-pole-single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a 16-pin Plastic DIP package with an operating temperature range of 0°C to +70°C. The device supports split supplies from ±5V to ±20V or a single positive supply from +5V to +30V. Key electrical parameters include a channel on-resistance of 60 Ω, a maximum turn-on time of 200 ns, and a maximum turn-off time of 150 ns. The component offers a 44V maximum breakdown voltage rating and low leakage currents typical of CMOS logic compatible inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Monolithic, low-power CMOS design providing reduced input loading and very low leakage currents.
• CMOS logic compatible inputs allowing direct interfacing with standard digital control circuits.
• Supports both single positive supply and bipolar split supply operation while maintaining signal integrity.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CJ+' against official documentation to confirm the plastic DIP package and commercial temperature grade. Ensure the ordering information matches the required voltage and current ratings for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required for signal routing in test or communications systems. Consider the 60 Ω on-resistance and switching speeds relative to the signal bandwidth requirements. Verify that the 16-pin DIP footprint fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG308A/DG309 family of quad SPST analog switches. The DG308A variant is normally open, whereas the DG309 is normally closed. Both share identical pinouts and electrical characteristics, differing only in their default state.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the DG308ADJ (SOIC package) and DG308ACK (CERDIP package). Other variants like the DG308AAK offer extended temperature ranges but require verification of package compatibility.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the DG308A and DG309?

The DG308A is a normally open (NO) SPST switch, while the DG309 is a normally closed (NC) SPST switch. They share the same pinout and electrical specifications.

Can the DG308ACJ+ operate with a single supply?

Yes, it can be used with a single positive supply ranging from +5V to +30V, although switching speed may be slower compared to split-supply operation.
