DG9421DV-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG9421DV-T1-E3 is a single-channel, single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It utilizes CMOS technology and operates within a supply voltage range of 2.7 V to 12 V for single-supply configurations, or ±1.35 V to ±6 V for dual-supply applications. The device features a maximum on-resistance of 3 Ohms and supports a DC switch current of 50 mA. Key switching parameters include a maximum turn-on time of 45 ns and a maximum turn-off time of 47 ns. Power dissipation is rated at 570 mW, with a maximum quiescent current of 1 µA. The component is housed in a TSOP-6 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix requirements against the official Vishay datasheet before ordering. Confirm that the TSOP-6 package dimensions align with your PCB footprint constraints. Ensure that the operating voltage limits are strictly observed to prevent device degradation. Check for any recent obsolescence notices or recommended alternative part numbers from the manufacturer.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a low on-resistance SPST switch is required for signals up to 12 V. Consider the 50 mA DC current limit for load handling capabilities. Evaluate the 45 ns switching speed against system timing requirements. Compare the TSOP-6 package size against available board space relative to other analog switches.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of analog switches from Vishay Siliconix. It serves as a discrete solution for managing analog signal paths in electronic circuits. The device complements other multi-channel switches by offering a dedicated single-switch option for simpler circuit topologies requiring minimal component count.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult the official Vishay documentation for verified replacement options. Cross-reference pinouts and electrical characteristics carefully. Ensure any substitute maintains compatibility with the 2.7 V to 12 V supply range and TSOP-6 package form factor.
