Overview
The DG186AA is a CMOS analog multiplexer manufactured by Harris Corporation. It integrates eight independent single-pole single-throw (SPST) switches on a single monolithic chip, providing a compact solution for signal routing applications. The device operates with low on-resistance and features fast switching speeds suitable for data acquisition systems. It supports both unipolar and bipolar signal ranges, offering flexibility in various electronic designs. The component utilizes standard CMOS technology to ensure compatibility with common logic families while maintaining low power consumption during operation.
Feature Summary
- Integrates eight independent SPST analog switches on a single chip
- Supports bidirectional signal transmission for flexible routing
- Features low on-resistance for minimal signal attenuation
- Compatible with standard digital logic control inputs
Applications
- Data acquisition systems requiring multi-channel signal selection
- Programmable gain amplifier circuits
- Sample and hold circuits
- Communication equipment signal routing
Procurement Notes
Verify the manufacturer origin as Harris Corporation or its successors, noting that original production may be discontinued. Confirm package type and pinout compatibility with existing board layouts. Check for RoHS compliance status if required for modern manufacturing standards. Ensure documentation references the specific DG186AA suffix rather than generic family variants.
Selection Notes
Select this component when eight isolated analog channels are needed within a single package footprint. Consider the operating voltage range and on-resistance specifications against system requirements. Evaluate thermal performance if multiple switches operate simultaneously under load. Verify logic input levels match the controlling microcontroller or FPGA outputs.
Part Context
Harris Corporation was a prominent semiconductor manufacturer known for analog and mixed-signal integrated circuits before its assets were acquired by other entities such as Intersil and subsequently Renesas. The DG186 series belongs to their line of CMOS analog switches, which were widely used in industrial and commercial electronics during the late twentieth century. This part represents a standard multiplexer configuration from that era.
Replacement Considerations
Publicly confirmed substitute part numbers for the DG186AA are not available in the provided reference material. Engineers should consult current distributor databases for cross-references from manufacturers like Maxim Integrated or Texas Instruments, ensuring functional equivalence in switch count, package, and electrical characteristics.
