DG506ABY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG506ABY is a single-ended multiplexer manufactured by Harris Corporation, featuring 16 channels and CMOS technology. It utilizes a CDIP28 package with a frit-sealed ceramic DIP construction. The device operates as a 16:1 analog switch, incorporating an internal digital decoder for channel selection and voltage reference logic thresholds. It supports direct interface with TTL and CMOS logic families without external pull-up resistors. The component is designed for harsh environments, offering dielectric isolation to prevent latch-up and ensuring low substrate leakage.

• Dielectric isolation process eliminates latch-up problems and reduces parasitic capacitance
• Internal +5V reference establishes guaranteed logic threshold levels for direct interfacing
• Digital inputs include series resistance and diode clamps for transient overvoltage protection

Analog Switches, Multiplexers, Demultiplexers Applications

• Harsh environment MIL-STD-883 Class Q applications
• Data acquisition systems requiring high channel density
• Industrial control systems with TTL/CMOS logic interfaces

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as the DG506AAK/883B designation appears across multiple vendors including Maxim, Vishay, and Renesas. Confirm that the specific DG506ABY part number corresponds to Harris Corporation specifications rather than generic equivalents. Ensure the ceramic DIP-28 package matches the required form factor for your assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a 16-channel single-ended multiplexer is required in a ruggedized ceramic package. The dielectric isolation feature makes it suitable for applications where standard junction-isolated CMOS devices might suffer from latch-up. Verify that the ±15V analog signal range meets your system's voltage requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the HI-506/HI-507 and HI-508/HI-509 monolithic CMOS multiplexer family. These devices integrate sixteen or eight analog switches with digital decoding circuits. The DG506ABY specifically represents the 16-channel variant within this architecture, providing a compact solution for multi-channel signal routing in demanding electronic environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public documentation confirms replacement of DG506A/DG506AA and DG507A/DG507AA variants. The JM38510/19001BXA (JAN version of HI-1-0506) serves as a qualified military-grade substitute. Verify pinout compatibility before substituting with other 16-channel CMOS multiplexers.
