Overview
The DG408DY-T is an 8:1 CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It routes one of eight inputs to a single common output using three binary address lines. The device operates with a single supply voltage ranging from 5V to 30V or dual supplies of ±5V to ±20V. Key electrical specifications include a maximum on-resistance of 100 ohms, switch times of 150ns for both turn-on and turn-off, and low charge injection of 2pC. It features a leakage current of 500pA and channel-to-channel matching of 1.5 ohms. The component is housed in a 16-SOIC package and supports an operating temperature range of -40°C to 85°C.
Feature Summary
- Configures as an 8:1 multiplexer to select one input signal for transmission to a common output based on digital address inputs.
- Utilizes CMOS technology to achieve low power consumption and high-speed switching capabilities suitable for data acquisition systems.
- Provides precise signal routing with low on-resistance and minimal charge injection to maintain signal integrity during transitions.
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Medical equipment signal conditioning
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check current lifecycle status as distribution availability may vary. Ensure the 16-SOIC package dimensions match the target PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when an 8:1 analog switching configuration is required within a 16-pin surface-mount package. Consider the 100-ohm on-resistance limit and 150ns switching speed against system timing constraints. Evaluate the ±5V to ±20V dual supply capability if bipolar signal handling is necessary for the application design.
Part Context
This part belongs to the DG408 series of improved CMOS analog multiplexers. It serves as a functional alternative to other variants like the DG408CY+ or DG408EUE+, differing primarily in packaging format. The DG408 family is designed for general-purpose analog signal routing applications where moderate speed and low power are prioritized.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific component were not identified in the provided source material. Verify compatibility with direct pin-for-pin replacements such as the DG408DY+ if available through official channels.
