DG302AAK/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG302AAK/883 is a dual-channel CMOS analog switch in a 14-pin CerDIP package. It features two double-pole single-throw (DPST) switches with a maximum on-resistance of 50 Ω at room temperature and full operating range limits. The device supports dual supply voltages up to ±15 V, enabling a full rail-to-rail analog signal range from -15 V to +15 V. Key dynamic parameters include a turn-on time of 300 ns and a turn-off time of 250 ns. Power dissipation is rated at 825 mW for the 14-pin ceramic package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized Vishay channels or certified distributors. Confirm the presence of the /883 suffix indicating military-grade screening standards. Check datasheet revision history for any updates to absolute maximum ratings or electrical characteristics prior to final design integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent DPST switching is required within a single package. Ensure the application environment stays within the specified -55 °C to +125 °C temperature range. Verify that the logic input levels are compatible with standard CMOS thresholds for reliable switching control.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG300A_MIL series, which includes SPST (DG300A), SPDT (DG301A), and DPST (DG302A) configurations. All variants share similar CMOS process technology and pinout compatibility within their respective channel counts. The series is designed for precision applications requiring low leakage and high isolation.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states that non-hermetic versions are obsolete and recommends the DG300B Series as pin-for-pin replacements. Verify if the hermetic /883 variant has a direct equivalent in newer Vishay portfolios or if the DG300B series meets the specific environmental requirements.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog signal range supported by the DG302AAK/883?

The device supports a full rail-to-rail analog signal range, allowing signals to swing from the negative supply rail (V-) to the positive supply rail (V+).

Does the DG302AAK/883 support single-supply operation?

Yes, single supply operation is allowed by connecting the V- rail to 0 V, although this may result in increased on-resistance and slower switching speeds.

What is the typical charge injection value for this component?

The typical charge injection is 8 pC, measured with a load capacitance of 1 nF and zero generator resistance.
