Overview
The DG308ADY+T is a monolithic CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features an 8-to-1 configuration, routing one of eight input channels to a single common output based on three binary address lines. The device operates with a single supply voltage ranging from 5 V to 30 V or dual supplies up to ±20 V. Key electrical parameters include a maximum on-resistance of 100 Ohms, a typical charge injection of -10 pC, and a maximum off-leakage current of 5 nA. Switching performance is characterized by a maximum turn-on time of 250 ns and a turn-off time of 150 ns. The component is housed in a 16-pin SOIC-Narrow package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides high-density signal routing through an 8:1 multiplexing architecture controlled by standard binary inputs.
- Features low charge injection characteristics suitable for precision analog signal switching applications.
- Supports wide single and dual power supply voltages to accommodate various system requirements.
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 as indicated by the '+' designation. Ensure the supplier provides valid traceability documentation for the Analog Devices/Maxim Integrated origin. Check for any obsolescence notices or lifecycle changes prior to final procurement decisions.
Selection Notes
Select this component when an 8-channel multiplexer is required within a narrow SOIC footprint. Compare against the DG308ACJ+ if through-hole DIP packaging is preferred instead of surface mount. Consider the DG309 variant if a complementary 4x SPST switch configuration is needed rather than a single 8:1 mux path.
Part Context
This part belongs to the DG308 family of CMOS analog switches. It serves as a surface-mount version of the legacy DG308 series, maintaining functional compatibility while adapting to modern PCB assembly techniques. The device integrates level-shifting circuitry to allow direct interface with TTL or CMOS logic controls.
Replacement Considerations
Public confirmed substitutes include DG308ADY-T1-E3 (Vishay) and DG308ACJ+ (Analog Devices). Verify pinout and package dimensions match before substitution.
