Overview
The DG387AAK/883 is a dual CMOS analog switch in a 14-pin CerDIP package. It operates with supply voltages up to ±20 V and supports full rail-to-rail analog signal ranges from -15 V to +15 V. The device features a maximum on-resistance of 50 Ω at room temperature, rising to 75 Ω across the full industrial range. Switching times are specified at 300 ns for turn-on and 250 ns for turn-off. Power dissipation is limited to 825 mW, with an operating temperature range of -55 °C to +125 °C.
Feature Summary
- Monolithic CMOS construction ensures low power consumption and excellent on/off performance.
- Break-before-make switching action prevents signal shorting during transitions.
- Epitaxial layer design provides immunity to latch-up conditions.
- Quasi TTL logic compatibility allows direct interfacing with standard digital control circuits.
Applications
- Instrumentation systems requiring precise signal routing
- Process control applications demanding fast switching speeds
- Programmable gain amplifier circuits
- Low level switching circuits in battery powered systems
Procurement Notes
Verify component authenticity through authorized Vishay channels or certified distributors. Confirm the specific suffix matches the required military-grade specifications. Review the datasheet revision history for any updates to electrical characteristics or mechanical dimensions before finalizing procurement orders.
Selection Notes
Select this component when single-supply operation is not required and high voltage handling is necessary. Ensure the system can accommodate the higher on-resistance compared to modern low-voltage alternatives. Verify that the 14-pin CerDIP footprint aligns with the existing PCB layout constraints and thermal management requirements.
Part Context
This part belongs to the DG38x series of monolithic CMOS analog switches designed by Vishay Siliconix. It shares functional compatibility with the JFET DG180 family while offering lower power consumption. The device is intended for high-reliability applications where hermetic sealing and wide temperature operation are critical requirements.
Replacement Considerations
The DG381B series is documented as a pin-for-pin replacement for non-hermetic versions. Verify if the specific application requires the hermetic properties of the AK/883 suffix or if a plastic equivalent suffices. Cross-reference switching speeds and leakage currents to ensure compatibility with existing circuit designs.
