DG305AAK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG305AAK/883B is a single-channel CMOS analog switch configured as a single-pole double-throw (SPDT) circuit. Manufactured by Analog Devices Inc./Maxim Integrated, it operates within a supply voltage range of 5 V to 18 V for both single and dual power configurations. The device features a maximum on-resistance of 50 Ohms and supports a DC switch current of 30 mA. It utilizes a CDIP-14 through-hole package and is qualified under MIL-STD-883 standards. Key timing specifications include a maximum turn-on time of 250 ns and a maximum turn-off time of 150 ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix AK/883B indicates military-grade qualification and ceramic packaging. Confirm availability status as this component may be subject to limited production runs or obsolete status. Ensure compatibility with existing MIL-STD-883 procurement channels and validate that the CDIP-14 package matches the target board layout requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when MIL-STD-883 compliance is mandatory for the application. Compare the 50 Ohm on-resistance against system signal integrity requirements. Verify that the 30 mA DC switch current capability meets load demands. Ensure the CDIP-14 footprint is available in the design library.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG305A series of analog switches. It shares functional similarities with other devices in the family but differs in packaging and qualification level. The /883B suffix specifically denotes adherence to military standards, distinguishing it from commercial variants like the DG305ACK which may have different temperature ranges or reliability ratings.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must maintain MIL-STD-883 qualification and CDIP-14 packaging. Evaluate the DG305ACK for pin compatibility, noting potential differences in operating temperature range. Verify that any substitute maintains the 50 Ohm on-resistance and 30 mA current handling capabilities.
