Overview
The HI1-0508A-2 is a fault-protected analog multiplexer manufactured by Maxim Integrated, now part of Analog Devices. It features an 8-channel single-ended configuration housed in a 16-pin ceramic DIP package. The device operates with a nominal negative supply voltage of -15 V and supports a wide temperature range from -55 °C to +125 °C. Key electrical specifications include a maximum on-resistance (Ron) of 1500 Ω and a typical off-isolation of 68 dB. The component is classified as non-RoHS compliant and carries an EAR99 export classification code.
Feature Summary
- Fault protection capabilities for analog signal paths
- High-temperature operation suitable for industrial environments
- Ceramic glass-sealed packaging for durability
Applications
- Industrial process control systems requiring high-temperature reliability
- Test and measurement equipment involving analog signal routing
- Harsh environment data acquisition systems
Procurement Notes
Verify RoHS compliance status prior to integration, as the HI1-0508A-2 is explicitly listed as non-compliant. Confirm that the ceramic DIP package dimensions align with the target PCB footprint. Ensure that the 1500 Ω on-resistance meets the signal integrity requirements of the specific application circuit. Check for any updated environmental regulations regarding leaded components in the destination market.
Selection Notes
Select this component when fault protection and extended temperature ranges are critical. The high on-resistance may limit suitability for low-voltage precision applications. Compare against the DG508 series if lower resistance or modern packaging is required. Verify that the single-ended configuration matches the system architecture. Consider availability constraints due to the legacy status of the non-RoHS designation.
Part Context
The HI1-0508A-2 belongs to the broader family of analog multiplexer switches produced by Maxim Integrated. It serves as a specialized variant designed for rugged applications where standard plastic packages might fail. The product line emphasizes robustness and fault tolerance. This specific model represents an older generation of CMOS analog switches utilizing ceramic construction for enhanced thermal stability compared to standard plastic equivalents.
Replacement Considerations
Publicly confirmed substitute part numbers for the HI1-0508A-2 were not identified in the provided documentation. Engineers should evaluate the DG508 series or MPC508AP for functional alternatives, noting differences in resistance, packaging, and compliance status.
