DG529DJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG529DJ+ is an 8-channel, differential CMOS multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features on-board address and control latches to simplify microprocessor-based designs. The device operates with dual supplies ranging from ±4.5V to ±20V or a single supply from +5V to +30V. It utilizes break-before-make switching to prevent signal shorting. The package is an 18-pin Plastic DIP (PDIP-18). The operating temperature range for the 'D' suffix is -40°C to +85°C. Electrical characteristics include a maximum drain-source on-resistance of 450Ω at TA = TMAX and 500Ω at TA = +25°C. Supply currents are typically 2.5mA positive and 0.01mA negative.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component marking against the official datasheet specifications to ensure authenticity. Confirm that the package type matches the required 18-pin Plastic DIP form factor. Check the temperature grade suffix to ensure it meets the operational environmental requirements of the target application. Validate RoHS compliance status through the manufacturer's documentation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG529DJ+ when a differential 2-of-8 multiplexing configuration is required rather than single-ended. Ensure the design supports the specified voltage ranges and thermal conditions. Consider the PDIP-18 package constraints for PCB layout. Verify compatibility with existing TTL/CMOS logic levels if interfacing directly with microprocessors.
