DG333ADJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG333ADJ-E3 is a precision quad single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of ±4 V to ±22 V or a single supply from 5 V to 40 V. The device features a maximum on-resistance of 45 Ω and a maximum turn-on time of 175 ns. It supports a continuous DC switch current of 30 mA and dissipates up to 890 mW in its 20-pin plastic DIP package. Designed for high accuracy, it minimizes measurement errors through low leakage and charge injection characteristics.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as End-of-Life (EOL) before initiating procurement. Confirm that the specific suffix matches the required package type and compliance standards. Review official documentation for any updates regarding availability or recommended alternatives due to manufacturing lifecycle changes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent SPDT channels are required in a through-hole DIP-20 package. Ensure the application supports the specified ±4 V to ±22 V dual supply or 5 V to 40 V single supply ranges. Verify that the 45 Ω maximum on-resistance meets the signal integrity requirements of the target circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG333A/DG333AL family of precision analog switches. The 'D' suffix indicates the 20-pin wide-body SOIC or plastic DIP package variant, while 'J' specifies the plastic DIP configuration. The '-E3' suffix denotes lead-free termination compliant with RoHS standards.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic truth table for the DG333ADJ-E3?

When the digital input is Logic '0' (≤ 0.8 V), switches SW1, SW4, SW5, and SW8 are normally open, while SW2, SW3, SW6, and SW7 are normally closed. When the input is Logic '1' (≥ 2.4 V), these states reverse.

How does the device handle overvoltage conditions?

Signals on the source (Sx), drain (Dx), or input (Inx) pins exceeding the positive supply (V+) or negative supply (V-) will be clamped by internal diodes. The forward diode current must be limited to the maximum ratings specified.

What is the typical charge injection performance?

The typical charge injection is 10 pC, measured with a load capacitance of 10 nF, a generator voltage of 0 V, and a generator resistance of 0 Ω at room temperature.
