DG201ACY

Analog Switches, Multiplexers, Demultiplexers Overview

The Intersil DG201ACY is a monolithic quad single-pole single-throw (SPST) normally-closed CMOS analog switch. It features four independent switches in a 16-pin ceramic DIP package. The device operates with dual supplies ranging from ±4.5V to ±18V or a single supply up to 36V. Key electrical parameters include a maximum on-resistance of 200 ohms, off-leakage current of 5nA, and charge injection of 20pC. Switching times are specified at 600ns for turn-on and 450ns for turn-off. The unit supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Monolithic CMOS construction provides low power consumption and high input impedance.
• Normally-closed configuration ensures defined signal paths when unpowered.
• TTL and CMOS logic compatible control inputs simplify interface design.
• Low distortion characteristics support precision analog signal routing.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation, as Intersil operations were acquired by Renesas Electronics. Confirm the specific suffix 'ACY' corresponds to the ceramic DIP package variant rather than plastic or surface-mount alternatives. Ensure the component meets required environmental standards for the intended deployment environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed analog switching function is required. Compare on-resistance and leakage specifications against alternative SPST switches if signal integrity is critical. Verify that the 16-pin DIP footprint matches the PCB layout constraints. Consider thermal dissipation requirements if multiple switches are activated simultaneously under load.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG201 belongs to a family of quad CMOS analog switches originally developed by Dallas Semiconductor and later Intersil. These devices are designed for general-purpose signal switching applications. The DG201 specifically offers normally-closed contacts, distinguishing it from the DG200 (normally-open) and DG202 (dual SPDT) variants within the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public documentation indicates that Vishay DG201B/202B devices serve as pin-for-pin replacements for obsolete non-hermetic versions. Verify electrical compatibility, particularly on-resistance and leakage specs, when substituting with these Vishay equivalents or other generic quad SPST CMOS switches.
