DG528AK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG528AK/883B is a high-reliability, military-grade CMOS latchable multiplexer switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an 8-channel to 1-line configuration housed in a rugged CDIP-16 package designed for through-hole mounting. The device operates on dual power supplies ranging from 4.5 V to 20 V or single supplies up to 30 V. Key electrical specifications include a maximum on-resistance of 450 Ohms, propagation delays of 1.5 us, and a maximum power dissipation of 889 mW. It supports a wide operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify authenticity through authorized distributors due to restricted availability. Confirm specific suffix requirements for radiation hardness or thermal performance. Check current stock levels as supply may be limited. Ensure compatibility with existing board layouts for the CDIP-16 package. Review datasheet for handling precautions regarding static sensitivity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when latchable switching is required in space-constrained military applications. Compare on-resistance and leakage current against system signal integrity needs. Verify voltage headroom for both control logic and analog signal paths. Consider thermal management capabilities within the sealed enclosure. Evaluate pinout compatibility if replacing legacy parts.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG528 series of latchable multiplexers. The AK/883B suffix denotes the military grade variant with specific screening and testing protocols. It shares functional similarities with commercial DG528 versions but offers enhanced durability and traceability for defense contracts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG528DJ+ is a commercial equivalent with similar pinout but lacks military certification. DG408AK/883B offers different channel configurations. Verify mechanical fit and electrical parameters before substitution.
