DG300ACJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG300ACJ is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of 0°C to +70°C and is housed in a 14-lead Plastic DIP package. The device supports dual power supplies from ±5V to ±18V or a single supply from +10V to +30V. Key electrical specifications include a maximum on-resistance of 50Ω, a turn-on time of 300ns, and a turn-off time of 250ns. Supply current is typically 0.5mA at positive rail and negligible at the negative rail.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'C' corresponds to the commercial temperature range of 0°C to +70°C. Confirm the 'J' suffix indicates the 14-lead plastic DIP package format. Ensure compatibility with existing PCB footprints for through-hole mounting. Check for RoHS compliance status if required by local regulations. Validate that the manufacturer designation matches the current Analog Devices or Maxim Integrated product line.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPST switching is required with TTL-compatible logic levels. The device is suitable for battery-powered applications due to its low power consumption. Consider the 50Ω maximum on-resistance for signal integrity requirements. Verify that the ±5V to ±18V supply range aligns with the system power architecture. Evaluate the 300ns switching speed against the application's timing constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG300ACJ belongs to the DG300A-DG303A family of TTL-compatible CMOS analog switches. This family includes dual SPST (DG300), dual SPDT (DG301), quad SPST (DG302), and quad SPDT (DG303) configurations. All devices in the series share electrical compatibility and pin-out similarities, facilitating design flexibility across different switching topologies within the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same family include DG300CJ for identical functionality. Other variants like DG301CJ offer SPDT configuration in the same package. Cross-manufacturer equivalents should be verified for pin compatibility and electrical parameter alignment. Ensure any substitute maintains the 14-lead PDIP form factor and commercial temperature rating.
