DG442DY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442DY-E3 is a quad single-pole single-throw (SPST) normally open CMOS analog switch manufactured by Vishay Siliconix. It operates on single or dual power supplies ranging from 5 V to 36 V single-ended, or ±2.5 V to ±18 V dual-supply configurations. The device features a typical drain-source on-resistance of 50 Ω and a maximum turn-on time of 250 ns. It utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latchup. The component is housed in a 16-pin narrow SOIC package and supports an operating temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E3' confirms lead-free compliance and RoHS standards as defined by Vishay. Confirm the 'DY' designation matches the required 16-pin narrow SOIC surface-mount package. Ensure the D-suffix rating aligns with the intended -40 °C to +85 °C industrial operating environment requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally open SPST configuration is required for upgrading legacy DG201A/DG202 sockets. Consider the 50 Ω typical on-resistance and low charge injection characteristics for precision applications. Verify that the 36 V absolute maximum voltage rating accommodates the system's peak signal levels without exceeding limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG44x series of monolithic quad analog switches. It shares the same physical footprint and pinout as the DG441 but differs functionally by providing a normally open state instead of a normally closed state. Both variants utilize the same high-voltage silicon-gate manufacturing process.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the DG442 switches?

The DG442 provides a normally open function, meaning the channels are off when the logic input is low.

How does the DG442 compare to the DG201A?

The DG442 is designed as a direct upgrade for DG201A/DG202 sockets, offering lower on-resistance and faster switching speeds.

Does the device support single-supply operation?

Yes, the DG442 supports single-supply operation with voltages ranging from 5 V to 36 V.
