Overview
The DG528EWN+T is an 8-channel multiplexer switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features a 1 x 8:1 configuration housed in an SOIC-Wide-18 surface-mount package. The device operates on a single supply voltage ranging from 5 V to 30 V, or dual supplies of +/- 4.5 V to +/- 20 V. Key electrical parameters include a maximum on-resistance of 450 Ohms, with both turn-on and turn-off times limited to 1.5 us. It supports a maximum power dissipation of 762 mW and functions within a temperature range of -40 C to +85 C.
Feature Summary
- Provides eight independent signal paths for multiplexing applications
- Supports latchable control inputs for stable state retention
- Compatible with standard TTL and CMOS logic families
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Automated test equipment signal routing
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm tape-and-reel packaging availability, as standard listings may indicate tube packaging. Confirm RoHS compliance status through current datasheets before procurement. Ensure the ordering code matches the required operating temperature range and package variant to avoid integration errors.
Selection Notes
Select this component when an 8-channel multiplexer with latchable inputs is required. Verify that the 450 Ohm on-resistance meets system signal integrity requirements. Check that the SOIC-Wide-18 footprint aligns with PCB layout constraints. Ensure supply voltages remain within the specified 5 V to 30 V single-supply limits.
Part Context
This part belongs to the DG528 series of analog multiplexer switches. It shares functional similarities with other devices in the family but is distinguished by its specific channel count and latchable input architecture. The component serves as a critical interface element for managing multiple analog signals within electronic circuits.
Replacement Considerations
Consult official substitution guides for compatible parts. Verify pinout compatibility and electrical specifications before replacing the original component.
