DG541DJ-E3

Analog Switches - Special Purpose Overview

The DG541DJ-E3 is a wideband video switch IC manufactured by Vishay Siliconix, housed in a 16-pin Plastic DIP package. It features four independent SPST channels with a 'T' switch configuration for low crosstalk and high off-isolation. The device operates on a single or dual supply ranging from -3 V to +15 V. Key electrical parameters include a maximum on-resistance of 60 Ohms, a bandwidth of 500 MHz, a maximum turn-on time of 70 ns, and a maximum turn-off time of 50 ns. It supports an analog signal range of ±5 V and maintains TTL/CMOS logic compatibility.

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for halogen-free certification according to IEC 61249-2-21. Ensure the specific ordering suffix matches the required package type and temperature range before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring wideband video signal routing with minimal distortion. The 16-pin DIP package suits through-hole prototyping or legacy board designs. Verify that the required supply voltage falls within the -3 V to +15 V range and that the load resistance requirements align with the specified bandwidth performance.

Analog Switches - Special Purpose Part Context

This part belongs to the DG540/DG541/DG542 family of wideband/video switches. While sharing similar internal architecture and D/CMOS processing technology, the DG541 differs from the DG540 by lacking extra ground pins between signal pins and from the DG542 by utilizing non-inverted control logic for its channels.

Analog Switches - Special Purpose Replacement Considerations

Public datasheets list the DG540DJ-E3 and DG542DJ-E3 as members of the same family. These parts share the same 16-pin DIP package but differ in pinout grounding schemes and logic inversion characteristics. Verify functional equivalence regarding control logic polarity and isolation requirements before substitution.

Analog Switches - Special Purpose FAQ

What is the maximum power dissipation for the 16-pin Plastic DIP package?

The maximum power dissipation is 470 mW at room temperature (25 °C), with a derating factor of 6.5 mW/°C above 25 °C.

How does the DG541 handle analog signal ranges relative to its power supplies?

With V+ = 12 V and V- = -5 V, the device can control AC signals up to ±5 V. The analog signal must not exceed V- by more than -0.3 V to prevent forward biasing the substrate p-n junction.

Is the DG541 compatible with standard digital logic families?

Yes, the device is built with an on-chip regulator circuit that maintains TTL and CMOS logic compatibility over the entire operating supply voltage range.
