DG542DJ-E3

Analog Switches - Special Purpose Overview

The DG542DJ-E3 is a wideband/video switch IC manufactured by Vishay Siliconix, housed in a 16-pin plastic DIP package. It features four SPDT channels built on D/CMOS technology with a 'T' switch configuration for low crosstalk and high off-isolation. Key electrical parameters include a bandwidth of 500 MHz, maximum on-resistance of 60 Ω at room temperature (up to 75 Ω over the full range), turn-on time of 100 ns, and turn-off time of 60 ns. The device operates within a supply voltage range of -3 V to +15 V, supports an analog signal range of ±5 V, and functions across a temperature range of -40 °C to +85 °C.

Analog Switches - Special Purpose Feature Summary

• Utilizes a proprietary 'T' switch configuration to achieve exceptionally low crosstalk and high off-isolation.
• Features bidirectional switching capability with interchangeable source and drain terminals.
• Incorporates an on-chip regulator circuit to maintain TTL logic compatibility across the operating supply voltage range.

Analog Switches - Special Purpose Applications

• RF and video signal switching
• RGB color signal routing
• Video multiplexing systems
• Fast data acquisition circuits

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing lot codes if required for traceability. Ensure the ordering suffix matches the desired package type and temperature rating before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-speed analog switching with minimal signal distortion. The 16-pin DIP package is suitable for through-hole prototyping or legacy board designs. Verify that the required analog signal amplitude falls within the specified limits relative to the chosen supply voltages.

Analog Switches - Special Purpose Part Context

This part belongs to the DG540/DG541/DG542 family of wideband switches from Vishay Siliconix. While functionally similar to the DG540 and DG541, the DG542 specifically offers complementary channel outputs where two channels are active while the other two are inactive based on the control logic state.

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Vishay resources for current alternative recommendations.

Analog Switches - Special Purpose FAQ

What is the typical off-isolation performance of the DG542?

The DG542 provides an off-isolation of approximately -75 dB at 5 MHz with a 75 Ω load resistance.

How does the DG542 handle bidirectional signals?

Each switch conducts equally well in both directions when on, allowing the source and drain terminals to be interchangeable for flexible circuit layout.

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

The maximum power dissipation for the 16-pin plastic DIP package is 470 mW at 25 °C, derating by 6.5 mW/°C above this temperature.
