Overview
The DG508ADY is a monolithic CMOS analog multiplexer featuring eight single-ended channels in a 1-of-8 configuration. It operates on dual supplies ranging from ±4.5V to ±18V and supports a single supply of 9V to 36V. The device guarantees break-before-make switching and latchup protection. Electrical characteristics at ±15V include a maximum on-resistance of 550Ω, a transition time of 1.5µs, and an enable turn-on time of 1.5µs. It is housed in a 16-pin Narrow SO package with an operating temperature range of -40°C to +85°C.
Feature Summary
- Monolithic CMOS design ensuring low power consumption and latchup-proof construction.
- Guaranteed break-before-make switching for reliable signal routing.
- Symmetrical, bidirectional operation compatible with TTL and CMOS logic inputs.
Applications
- Data-acquisition systems
- Signal routing
- Control systems
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the selected variant matches the required voltage and current specifications for the target application environment.
Selection Notes
Select this component for applications requiring high channel density in a small surface-mount footprint. Verify that the system voltage falls within the ±4.5V to ±18V dual supply or 9V to 36V single supply range. Consider the 550Ω maximum on-resistance when designing for low-signal integrity requirements.
Part Context
This device belongs to the DG508A/DG509A family of monolithic CMOS analog multiplexers. The DG508A specifically provides an 8-channel single-ended configuration, whereas the DG509A offers a differential 4-channel setup. Both share similar electrical characteristics and packaging options.
Replacement Considerations

FAQ
Does the DG508ADY support single-supply operation?
Yes, the device can operate with a single supply ranging from 9V to 36V, although the minimum operating voltage for the DG508ADY/MY variants is specified as ±9V.
What is the guaranteed switching behavior of the DG508ADY?
The device guarantees break-before-make switching, ensuring that one channel disconnects before another connects during transitions.
Is the DG508ADY susceptible to latchup?
No, the device features latchup-proof construction and is guaranteed not to latch up even if power supplies are turned off while input signals are present.
