Overview
The DG528CJ is an 8-channel analog multiplexer switch manufactured by Analog Devices Inc./Maxim Integrated. It features a single 8:1 circuit configuration housed in an 18-pin PDIP package with a width of 0.300 inches (7.62 mm). The device supports single supply voltages ranging from 5V to 30V and dual supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 450 ohms, channel-to-channel matching of 27 ohms, and a charge injection of 4pC. Switching times are specified at 1.5µs for both turn-on and turn-off. Leakage current is limited to 5nA maximum, with off-channel capacitance values of 5pF and 25pF.
Feature Summary
- Provides latchable multiplexing functionality for signal routing applications
- Offers low charge injection characteristics suitable for precision data acquisition systems
- Supports wide single and dual power supply voltage ranges for flexible integration
Applications
- Data acquisition systems requiring multi-channel signal selection

Procurement Notes
Verify the specific suffix designation when ordering, as it determines the package type and temperature range. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to procurement. Ensure the selected variant matches the required thermal operating conditions for the intended application environment.
Selection Notes
Select this component when an 8-channel analog switch with latchable inputs is required. Verify that the 450-ohm on-resistance meets system loss requirements. Check compatibility with available logic levels for address line control. Ensure the 18-PDIP package fits the PCB layout constraints and thermal management strategy.
Part Context
This part belongs to the DG528/529 family of CMOS analog multiplexers. It serves as a general-purpose switching solution for connecting multiple analog signals to a single processing path. The device is designed for applications demanding low power consumption and high reliability in industrial and commercial environments.
Replacement Considerations
Direct replacements may include other 8-channel CMOS multiplexers from the same manufacturer family. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult official datasheets for any functional differences in latch behavior or drive capability.
