DG508AEWE+

Overview

The DG508AEWE+ is a monolithic CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It functions as a single 8-channel (1-of-8) switch with bidirectional signal routing capabilities. The device operates on dual power supplies ranging from ±4.5V to ±18V and supports an analog signal range of -15V to +15V. Key electrical parameters include a maximum drain-source on-resistance of 450 Ohms at ±15V, with a maximum switching transition time of 1.0µs. The component features latchup-proof construction and guarantees break-before-make switching. It is housed in a 16-pin Wide SO package and operates within a temperature range of -40°C to +85°C.

Feature Summary

Monolithic low-power CMOS design ensuring continuous operation across specified supply ranges
Latchup-proof construction allowing safe operation even if power supplies are turned off while input signals remain present
Guaranteed break-before-make switching to prevent signal shorting during channel transitions
TTL and CMOS compatible logic and enable inputs for flexible digital control

Applications

Data-acquisition systems requiring precise signal routing
Control systems utilizing sequential multiplexing
Aircraft heads-up displays demanding reliable analog switching
Data logging systems needing high isolation between channels

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. Ensure that the plus (+) designation aligns with RoHS compliance requirements for your assembly process. Cross-reference the part number with official distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a single 8-channel multiplexer with wide dual-supply voltage support is required. The Wide SO package is suitable for surface-mount applications where thermal dissipation characteristics must be evaluated against the derating curve. Consider the 450 Ohm maximum on-resistance limit when designing circuits sensitive to signal attenuation or voltage drop across the switch.

Part Context

This device belongs to the DG508A/DG509A series of monolithic CMOS analog multiplexers. The DG508A variant specifically provides a single 8-channel configuration, whereas the DG509A offers differential 4-channel operation. Both share similar architectural features but differ in channel count and output configuration. The DG508AEWE+ represents the industrial temperature grade version packaged in a Wide SO format.

Replacement Considerations

Direct pin-compatible replacements within the same family include the DG508ADJ+ (Plastic DIP) and DG508ADY+ (Narrow SO). For improved performance metrics such as lower on-resistance and faster switching speeds, consider upgrading to the MAX338 or MAX339 series, though these may require circuit redesign due to different voltage specifications.
