DG423DY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG423DY+T is a dual single-pole single-throw (SPST) normally open analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a single supply voltage range of 10V to 30V or dual supplies of ±4.5V to ±20V. The device features a maximum on-resistance of 35 ohms and a channel-to-channel matching of 3 ohms. Switching times are specified at a maximum of 250ns for turn-on and 200ns for turn-off. Key electrical characteristics include a charge injection of 10pC, off-state leakage current of 500pA, and crosstalk of -90dB at 1MHz. It is housed in a 16-SOIC package and supports an operating temperature range from -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as discontinued before procurement planning. Confirm the specific suffix 'T' indicates tape and reel packaging if required for automated assembly. Ensure compatibility with existing design constraints given the end-of-life status. Check for available alternative packages or pin-compatible replacements from the manufacturer's portfolio.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent analog switches are required with moderate speed and low on-resistance. Consider the 16-SOIC package size for PCB layout constraints. Evaluate the ±4.5V to ±20V dual supply capability against system power requirements. Compare charge injection specifications against other devices if signal fidelity is critical.
