DG202BAK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG202BAK is a quad CMOS analog switch manufactured by Vishay Siliconix, housed in a 16-pin CDIP package. It features four independent single-pole single-throw (SPST) channels. The device supports dual supply voltages ranging from ±4.5 V to ±22 V or a single supply up to 12 V. Key electrical parameters include a maximum on-resistance of 85 Ω, a maximum leakage current of 1 nA at +25°C, and a power dissipation of 900 mW. Switching times are specified with a maximum turn-on time of 200 ns and a maximum turn-off time of 150 ns. The component operates within a temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'AK' against the manufacturer's official datasheet to confirm the exact package variant and termination type. Confirm RoHS compliance status as historical data may vary. Check for obsolescence notices directly from Vishay, as this component has been identified as discontinued in some distributor records. Ensure the CDIP-16 package availability aligns with current manufacturing capabilities.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG202BAK when a quad SPST configuration is required with high reliability over extended industrial temperatures. Compare the 85 Ω on-resistance against application requirements; lower resistance options exist in the DG201 series. Verify that the 200 ns switching speed meets system timing constraints. Consider the through-hole CDIP package if PCB layout requires manual insertion or specific mechanical mounting standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG202BAK belongs to the DG series of enhanced analog switches from Vishay Siliconix. This family typically offers improved performance metrics compared to earlier generations, such as reduced leakage and consistent on-resistance. The part represents a standard solution for general-purpose analog signal switching in legacy and industrial designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG202BDQ is a surface-mount alternative within the same functional family. For higher speed requirements, the DG201HSDQ-T1 offers faster switching times but different packaging. Verify pin compatibility before substituting any cross-package variants.
