DG301ACK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG301ACK is a high-speed, low distortion analog switch manufactured by Harris Corporation. It features a single SPDT configuration with a CMOS-compatible control interface. The device operates from dual supplies ranging from ±5V to ±20V or a single supply of 10V to 40V. Key electrical parameters include an on-resistance (Ron) of typically 10 ohms and a channel-to-channel matching of 0.1 ohm. Breakdown voltage exceeds 20V, while leakage current remains below 1nA at maximum ratings. Switching times are characterized by 60ns turn-on and 40ns turn-off delays.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• CMOS-compatible logic inputs for direct interfacing with standard digital systems
• Low on-resistance ensures minimal signal attenuation in the pass state
• High breakdown voltage capability protects against overvoltage conditions
• Fast switching speeds support high-frequency signal routing applications

Analog Switches, Multiplexers, Demultiplexers Applications

• Multiplexing audio and video signals in communication equipment
• Sample-and-hold circuits in data acquisition systems
• Programmable gain amplifiers requiring precise signal path selection
• Instrumentation systems needing isolated signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer source carefully as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently by Renesas Electronics. Ensure the component matches the original Harris specification sheet rather than later rebranded versions which may have subtle parameter variations. Confirm package integrity and date code authenticity through authorized distributors.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT switch with fast switching speed and low distortion is required. Compare Ron stability across temperature ranges if precision is critical. Consider pin compatibility with existing PCB layouts. Verify that the control voltage levels match the system logic family without additional level shifting circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Harris DG series of analog switches, known for their performance in professional audio and test equipment. The DG301 series was widely used before industry consolidation. Understanding its lineage helps in sourcing replacements and interpreting legacy documentation accurately.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the CD4051B for multiplexing needs, though with slower speeds. For exact functional replacement, check Intersil ISL40808 or similar CMOS analog switches. Verify on-resistance and leakage specs match original requirements before substitution.
