DG201ABY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201ABY is a quad single-pole single-throw (SPST) analog switch manufactured by Harris Corporation, part of the DG series. It features four independent channels with a maximum on-resistance of 50 ohms and operates within a supply voltage range of 10.8 V to 16.5 V for single supplies or ±7.5 V for dual supplies. The device supports a continuous DC switch current of 30 mA and includes overvoltage protection up to ±30 V. Key timing parameters include a maximum turn-on time of 60 ns and a maximum turn-off time of 50 ns. It is designed for operation across an extended temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation as Harris Corporation against current ownership records, noting that Vishay acquired Siliconix assets which included this product line. Confirm RoHS compliance status and specific package availability through authorized distributors, as legacy components may have limited stock or require alternative sourcing strategies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST analog switch with low on-resistance and high-speed switching is required. Ensure the operating voltage aligns with the 10.8 V to 16.5 V single-supply specification. Consider thermal dissipation limits if multiple channels are active simultaneously under load conditions exceeding typical ratings.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG201ABY belongs to the DG series of analog switches, originally developed by Harris Semiconductor before its acquisition by Intersil and subsequently by Renesas. This series is characterized by CMOS technology offering low power consumption and high input impedance. The ABY suffix typically denotes a specific package variant, often a plastic DIP, distinguishing it from surface-mount options like TSSOP or SOIC found in other variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include the DG201BDJ-E3 from Vishay/Siliconix, which shares similar electrical characteristics but may differ in package type. Verify pin compatibility and on-resistance specifications when substituting with generic quad SPST switches from other manufacturers.
