DG442LDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442LDY is a precision monolithic quad SPST low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies from ±3 V to ±6 V. The device features a typical on-resistance of 17 Ω and fast switching times with turn-on at 20 ns and turn-off at 12 ns. It offers low leakage current of 0.25 nA, 2000 V ESD protection, and TTL/CMOS compatibility. The component is housed in a 16-pin narrow SOIC package and supports an operating temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'LDY' against the official Vishay ordering information to confirm the 16-pin narrow SOIC package and -40 °C to +85 °C temperature grade. Ensure compliance with RoHS Directive 2002/95/EC requirements as stated in the datasheet specifications before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage operation and high-speed signal switching. The DG442L provides opposite control logic compared to the DG441L; verify that the active-low configuration matches the system design requirements. Consider the 17 Ω on-resistance and 0.25 nA leakage for precision signal integrity.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG442LDY belongs to the DG441L/DG442L series of precision monolithic quad SPST low-voltage CMOS analog switches. These devices are designed as companion parts with improved performance over industry standards, utilizing BiCMOS wafer fabrication technology for enhanced speed and lower power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG441LDY-E3 serves as a logical alternative if inverted logic control is required instead of the standard active-high configuration found in the DG442L series.
