DG307AAK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG307AAK is a monolithic CMOS analog switch from the DG304A through DG307A series, manufactured by Vishay Siliconix. It features two single-pole double-throw (SPDT) channels housed in a 14-pin CerDIP package. Designed for high-speed switching with a turn-on time of 110 ns and off-isolation of 62 dB, it supports full rail-to-rail analog signal ranges up to ±15 V. The device operates on dual or single supplies, drawing micropower currents as low as 30 nW. Built on the PLUS-40 CMOS process, it includes an epitaxial layer to prevent latchup and guarantees break-before-make switching action.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity upon receipt, as this part number may be subject to obsolescence or limited availability. Confirm that the physical package matches the 14-pin CerDIP specification and check for any manufacturer-specific markings indicating production origin. Ensure storage conditions adhere to the specified temperature limits to maintain ceramic seal integrity before installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG307AAK when SPDT configuration is required alongside fast switching speeds and low power consumption. This specific suffix denotes the military-grade temperature range (-55°C to +125°C) and hermetic ceramic packaging. Verify that the application requires the specific channel count and supply voltage capabilities defined in the datasheet electrical characteristics table.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG304A/305A/306A/307A family of monolithic CMOS switches. While sharing core architecture and performance metrics, the DG307AAK specifically provides two SPDT channels. Other members of the series offer different configurations, such as quad SPST or single SPDT variants, allowing designers to choose based on precise channel requirements within the same footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

For non-hermetic applications, plastic DIP versions like the DG307ACJ are available. Military specifications JM38510/11608BCA may serve as equivalent replacements if strict environmental sealing is not required. Always verify pin compatibility and thermal dissipation ratings before substituting.
