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.
Feature Summary
- CMOS technology enabling low power consumption and high input impedance
- Single-pole double-throw (SPDT) configuration for signal routing
- Wide dual-supply operation capability for flexible system integration
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal switching applications
- Test and measurement equipment signal paths
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.
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.
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.
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.
