ADG506ATQ/883B

The Analog Devices ADG506ATQ/883B is a monolithic CMOS 16-channel single-ended analog multiplexer that routes one of sixteen inputs to a common output under the control of a 4-bit binary address and an enable pin. Fabricated on an advanced oxide-isolated process, the device delivers low on-resistance with tight channel-to-channel matching, break-before-make switching action, and ultra-low quiescent power consumption. Digital inputs are fully TTL and CMOS compatible, while dielectric isolation enhances latch-up immunity and ESD ruggedness. Packaged in a hermetically sealed 28-pin Ceramic Dual Inline Package (CDIP), this variant is screened to MIL-STD-883 Class B standards, ensuring reliable operation over the full military temperature range and under severe environmental stress.

Typical deployments encompass high-reliability data acquisition systems, flight-critical instrumentation, avionics signal routing, and defense-grade automatic test equipment where multiplexing of multiple sensor or transducer channels is required without compromising signal integrity. In aerospace telemetry and industrial process control, the device performs precision channel scanning for strain gauges, thermocouples, and pressure transducers. The /883B suffix mandates rigorous military screening, including burn-in, thermal cycling, and hermeticity testing, which provides procurement teams with verified lot traceability and conformance to demanding source control drawings. As a mature Analog Devices multiplexer, obsolescence management and authorized distribution are key supply chain factors; verifying production status, lead times, and export classification mitigates long-term risk for programs requiring extended lifecycle support.
