Overview
The DG417AK/883B is a single-channel, SPST-NC CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 10V to 30V for single supply or ±4.5V to ±20V for dual supply configurations. The device features a maximum on-resistance of 35 Ohms and a channel-to-channel matching of 3 Ohms maximum. Key switching parameters include a maximum turn-on time of 175ns and a turn-off time of 145ns. It utilizes an 8-CERDIP package with through-hole mounting and supports an operating temperature range from 0°C to 70°C.
Feature Summary
- Single-pole, single-throw normally-closed (SPST-NC) configuration for signal routing
- Low on-resistance of 35 Ohms with tight channel-to-channel matching
- High isolation performance with -85dB crosstalk at 1MHz
- Low leakage current capability with maximum off-state leakage of 250pA
Applications
- Signal multiplexing in data acquisition systems
- Audio signal path switching
- Test and measurement equipment input selection
- Industrial control system I/O modules
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm that the specific suffix /883B meets required military or high-reliability specifications if applicable. Check for RoHS compliance requirements against EAR99 classification. Ensure packaging integrity for ceramic DIP components during handling.
Selection Notes
Select this component when a normally-closed state is required upon power-up or reset conditions. Compare on-resistance stability across temperature ranges against alternative SPST switches. Evaluate pin compatibility with existing 8-pin ceramic DIP footprints. Consider charge injection characteristics for precision analog applications requiring minimal signal distortion.
Part Context
This part belongs to the DG417 series of analog switches, designed for general-purpose signal switching applications. The /883B suffix typically indicates a specific reliability or screening level, often associated with military or aerospace standards, distinguishing it from commercial grade variants. It represents a legacy component within the broader Maxim Integrated portfolio of analog interface solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameter equivalence before considering any generic SPST-NC CMOS switch replacements.
