DG458AZ/883

Overview

The DG458AZ/883 is a high-speed, quad single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It features a military-grade /883 suffix indicating compliance with MIL-PRF-38534 standards. The device operates on dual supplies ranging from ±4.5 V to ±22 V or a single supply up to 12 V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a typical bandwidth of 70 MHz, and propagation delays of 300 ns (on) and 200 ns (off). It supports a continuous DC switch current of 30 mA and dissipates up to 900 mW in a CDIP-16 package.

Feature Summary

Quad SPDT configuration for multi-channel signal routing
High-speed switching with 70 MHz bandwidth capability
Military-grade reliability under MIL-PRF-38534 specifications

Applications

Military communication systems requiring rugged analog switching
Test and measurement equipment needing low distortion signal paths
Instrumentation channels for data acquisition systems

Procurement Notes

Verify the specific revision level and lot traceability when sourcing this component, as it adheres to military procurement standards. Confirm that the /883 designation matches the required MIL-PRF-38534 quality level. Ensure the CDIP-16 ceramic package integrity is maintained during handling to prevent mechanical stress damage.

Selection Notes

Select this part when high channel count and speed are required in a hermetic package. Compare against the DG458AJ/883 if lower on-resistance is needed. Verify that the 85 Ohm on-resistance meets system loss requirements. Check thermal dissipation limits relative to ambient temperature constraints in the final enclosure design.

Part Context

This component belongs to the DG45x series of high-speed analog switches. It shares functional similarities with the DG458AJ/883 but differs in performance grades. The /883 suffix distinguishes it from commercial variants like the DG458AN, ensuring suitability for harsh environments where standard plastic packages would fail.
