Overview
The DG508AC/D is a monolithic CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features an 8:1 configuration with eight signal channels and one common output, housed in a 16-pin DIP package. The device operates on dual power supplies ranging from ±4.5V to ±18V or a single supply of 9V to 36V. Key electrical specifications include a maximum on-state resistance of 450 Ohms, a channel-to-channel matching of 27 Ohms, and a leakage current of 1nA. Switching times are specified at 1.5µs for turn-on and 1µs for turn-off, with an operating temperature range of 0°C to +70°C.
Feature Summary
- Monolithic CMOS construction ensures low power consumption and high input impedance.
- Integrated logic interface allows direct connection to standard TTL or CMOS logic families.
- High isolation between channels minimizes crosstalk in multi-signal applications.
Applications
- Data acquisition systems requiring signal routing.
- Process control instrumentation for sensor switching.
- Industrial automation equipment involving analog signal management.
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected variant meets the required voltage and temperature specifications for the target application environment before finalizing procurement decisions.
Selection Notes
Select this component when an 8-channel analog switch with through-hole mounting is required. Consider the 450 Ohm on-resistance limit and the 0°C to +70°C industrial temperature range during circuit design. Verify that the logic levels used for control signals are compatible with the device's input thresholds.
Part Context
This part belongs to the DG508A series of analog multiplexers. The 'AC' suffix typically denotes commercial grade performance with a 0°C to +70°C operating range, while the '/D' indicates the 16-lead plastic DIP package style. This distinguishes it from other variants such as the ADY (SOIC) or AJ (PDIP) packages within the same functional family.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific component were not identified in the provided source material. Engineers should consult official cross-reference guides or contact the manufacturer directly for validated alternatives.
