DG445DJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG445DJ-E3 is a high-speed quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features four independent channels in a 16-pin DIP package, supporting both single and dual power supplies with voltage ranges of 5 V to 36 V for single supply and ±5 V to ±20 V for dual supply. The device exhibits a maximum on-resistance of 85 Ohms, a maximum power dissipation of 450 mW, and a maximum supply current of 1 µA. Switching performance includes a maximum turn-on time of 250 ns and a maximum turn-off time of 210 ns. It operates within a temperature range of -40 °C to +85 °C and supports a DC switch current of 30 mA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DJ' confirms the 16-pin PDIP package and through-hole mounting style required for your design. Confirm RoHS compliance status via the manufacturer's official documentation before finalizing procurement. Check current lifecycle status as distribution availability may vary by region.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog signal paths are needed in a through-hole layout. Ensure the application voltage does not exceed the 36 V single-supply limit. Verify that the 85 Ohm on-resistance meets the signal integrity requirements of the target circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of CMOS analog switches from Vishay Siliconix. It is the DIP-package variant of the DG445 family, offering equivalent electrical characteristics to surface-mount versions like the DG445DY-E3 but designed for printed circuit board insertion.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG445DY-E3 serves as a direct functional substitute with identical electrical specifications but utilizes an SOIC-16 surface-mount package instead of the DIP-16 form factor.
