Overview
The DG333ALDW-T1-E3 is a precision quad single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It integrates four independently controlled switches in a 20-pin wide-body SOIC package shipped in tape and reel format. The device supports dual supply voltages ranging from ±4 V to ±22 V, with a maximum single supply of 40 V. Key electrical parameters include a maximum on-resistance of 45 Ω at room temperature, rising to 90 Ω across the full operating range. Turn-on time is specified at a maximum of 175 ns, while turn-off time reaches 145 ns. The component operates within a temperature range of -40 °C to +85 °C.
Feature Summary
- Features micro-power operation with typical supply current below 1 μA for battery-powered applications
- Provides low leakage current of 20 pA typical value to minimize measurement errors
- Offers low charge injection performance to maintain signal integrity during switching
Applications
- Audio switching systems
- Test equipment signal routing
- Portable instrumentation
- Communication systems
- Switched-capacitor networks
Procurement Notes
Verify the complete part number including the suffix to confirm the specific package type and shipping method. The '-T1' designation indicates tape and reel packaging, which differs from tube-shipped variants. Confirm RoHS compliance status through official documentation as specifications may be subject to change without notice.
Selection Notes
Select this component when low power consumption and high precision are required for analog signal routing. Ensure the application voltage does not exceed the absolute maximum ratings of 40 V single supply or ±22 V dual supply. Verify that the thermal dissipation requirements fit within the 800 mW package limit for the SOIC-20 configuration.
Part Context
This part belongs to the DG333A/DG333AL family of precision analog switches. The 'AL' suffix denotes the low-power variant compared to the standard DG333A. The DW suffix identifies the wide-body SOIC package, while T1 specifies the tape and reel shipping configuration used for automated assembly processes.

FAQ
What is the maximum break-before-make time delay?
The datasheet specifies a minimum break-before-make time delay of 5 ns.
How does the on-resistance vary with temperature?
The maximum on-resistance increases from 45 Ω at room temperature to 90 Ω across the full operating temperature range of -40 °C to +85 °C.
Is the logic supply voltage separate from the main power supply?
Yes, the DG333AL includes a dedicated logic supply pin (VL) that allows for independent control of the input logic levels relative to the analog signal rails.
