DG458AK/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG458AK/883 is a high-performance analog multiplexer manufactured by Vishay Siliconix, housed in a CDIP-16 package. It features fault protection on all inputs and outputs, allowing operation with signals exceeding the supply rails without damage. The device integrates eight single-ended channels or four differential channels. Key electrical parameters include an on-resistance of 120 ohms maximum, a supply voltage range of ±15V to ±22V for dual supplies, and switching times of 1 microsecond max for both turn-on and turn-off. It operates within a temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrated fault protection circuitry safeguards internal components against input or output voltages that exceed the power supply limits.
• Configurable architecture supports either eight single-ended or four differential signal paths for versatile system integration.
• High reliability construction designed for demanding environments with extended industrial temperature ratings.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors due to military-grade specifications. Confirm RoHS compliance status and specific lot traceability requirements. Check current availability as this part may be subject to long-term supply constraints or obsolescence notices from the manufacturer.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is critical for system integrity during abnormal operating conditions. Ensure the required channel count matches the eight single-ended or four differential configuration. Verify that the 120-ohm on-resistance meets signal fidelity requirements for the application bandwidth.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG458 series of fault-protected analog multiplexers. It shares functional similarities with other DG series devices but is distinguished by its comprehensive fault tolerance capabilities. The /883 suffix indicates compliance with MIL-PRF-38534 standards for high-reliability integrated circuits.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes must maintain identical fault protection characteristics and pinout compatibility. Consider parts from the same DG458 family with different suffixes if packaging variations are acceptable. Verify thermal and electrical equivalence before substitution.
