Overview
The DG201AAK/883B is a monolithic quad SPST CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for military and aerospace applications. It features four independent single-pole switches in a 16-pin ceramic dual in-line package (CDIP). The device operates with supply voltages ranging from ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 250 ohms, an off-leakage current of 0.1 nA, and a charge injection of 20 pC. It supports signal levels up to ±15V and functions within a temperature range of -55°C to +125°C.
Feature Summary
- Hermetic ceramic packaging suitable for harsh environments
- TTL and CMOS logic compatibility
- Low off-state leakage current
- Wide input voltage range
Applications
- Military communication systems
- Aerospace data acquisition
- High-reliability test equipment
Procurement Notes
Verify authenticity through authorized distributors or direct manufacturer channels due to the component's specialized military grade status. Confirm the specific suffix indicates hermetic construction. Request full traceability documentation including lot codes and material declarations. Ensure compliance with relevant defense standards before integration into sensitive hardware designs.
Selection Notes
Select this component when high reliability and radiation hardness are required. Compare against standard commercial variants if environmental constraints allow. Verify pinout compatibility with existing PCB layouts. Consider thermal management requirements given the ceramic package characteristics and power dissipation limits under extreme operating conditions.
Part Context
This part belongs to the DG201 family of analog switches, specifically the ruggedized /883B variant compliant with MIL-STD-883. It serves as a robust alternative to commercial plastic-packaged versions for defense and space missions where failure is not an option.
Replacement Considerations
The DG201B series is documented as a pin-for-pin replacement for non-hermetic versions. For the /883B variant, verify specific military-grade equivalents directly with the manufacturer. No other public substitutes are confirmed.
