DG387ACJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG387ACJ is a single-channel SPDT CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 10 V to 30 V for single supplies, or ±5 V to ±18 V for dual supplies. The device features a maximum on-resistance of 50 Ohms and supports a DC switch current of 30 mA. Switching times are specified with a maximum turn-on time of 300 ns and a maximum turn-off time of 250 ns. It is housed in a 14-pin PDIP package and is rated for an operating temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions align with manufacturer specifications to maintain device integrity during handling and installation processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT switch with wide temperature tolerance is required. Verify that the 50 Ohm on-resistance meets circuit loss requirements. Ensure the 30 mA DC switch current capacity is sufficient for the intended load. Confirm compatibility with the 14-pin PDIP footprint during PCB layout design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG387A series of CMOS analog switches. It shares functional similarities with other devices in the family but differs in channel count and package options. The ACJ suffix indicates a specific commercial grade variant within the broader product line, distinguished by its through-hole packaging and extended temperature range capabilities compared to standard industrial versions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG387AAK/883B for military-grade ceramic DIP packages. Other compatible alternatives may include the DG381ACJ+ for dual SPST configurations if pinout adjustments are acceptable. Verify electrical parameters and package dimensions before substitution.
