Overview
The DG528CWN+ is an 8-channel, single-ended CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features on-board address and control latches to simplify microprocessor interfacing. 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 (rDS(ON)) of 400Ω at TA = TMAX, channel-to-channel matching (ΔrDS(ON)) of 1Ω, and charge injection of 4pC. Switching times are typically 1.5µs for turn-on and 1.5µs for turn-off. The component is housed in an 18-pin Wide SOIC package and supports an operating temperature range of 0°C to +70°C.
Feature Summary
- On-board address and control latches reduce board space and simplify design in microprocessor-based applications.
- Break-before-make switching prevents momentary shorting of input signals during channel transitions.
- TTL and CMOS logic compatible digital inputs ensure broad interface compatibility.
Applications
- Data-acquisition systems
- Automatic test equipment
- Avionics and military systems
- Communication systems
- Microprocessor-controlled systems
Procurement Notes
Verify the specific suffix 'CWN+' against official documentation to confirm the 18-Wide SOIC package and commercial temperature grade. Ensure that the ordering information matches the required voltage and logic specifications for the target application environment.
Selection Notes
Select this component when latchable 8-channel multiplexing is required within a standard 18-pin surface-mount footprint. Verify that the system power supply falls within the specified single or dual rail ranges and that the thermal environment remains within the 0°C to +70°C operational limits.
Part Context
This part belongs to the DG528/DG529 family of monolithic CMOS multiplexers. The DG528 variant provides single-ended switching, whereas the DG529 offers differential channels. Both share identical pinouts and control logic structures, differing primarily in internal channel configuration.
Replacement Considerations
The datasheet confirms pin and electrical compatibility with industry-standard DG528/DG529 devices as well as ADG528/ADG529 variants. Verify that any substitute maintains the same latch functionality and on-resistance characteristics.
