DG529CJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG529CJ+ 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. Key electrical parameters include a maximum drain-source on-resistance of 450Ω at TA = TMAX, a switching time of 1.5µs, and a charge injection of 4pC. It is housed in an 18-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific suffix indicates the lead-free (+) status and the 'C' grade for commercial temperature operation. Ensure the procurement source provides valid traceability data consistent with Analog Devices specifications. Cross-reference the ordering information table in the datasheet to validate the package type and temperature range before finalizing acquisition.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG529CJ+ when a differential 2-of-8 multiplexing configuration is required rather than the single-ended DG528 variant. Consider this part for applications needing latchable address inputs to interface directly with microprocessor buses without external latching hardware. Verify that the system power supply constraints align with the specified ±4.5V to ±20V dual or +5V to +30V single supply ranges.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG529CJ+ belongs to the DG528/DG529 family of monolithic CMOS multiplexers. It is pin and electrically compatible with industry-standard equivalents such as the ADG529. The 'CJ' suffix denotes the commercial temperature range (0°C to +70°C) and the 18-pin Plastic DIP package format, distinguishing it from wide SO or ceramic variants within the same functional family.
