Overview
The HI1-1818A-2 is a monolithic, single-ended, 8-channel CMOS analog multiplexer manufactured by Renesas Electronics Corporation. It features built-in channel selection decoding and an inhibit input to disable all channels simultaneously. The device utilizes Dielectric Isolation (DI) processing to minimize substrate leakage and parasitic capacitance, ensuring low static errors and high throughput rates. Key electrical specifications include a maximum ON resistance of 500Ω across the full temperature range, a typical access time of 350ns, and a wide analog signal range supporting ±15V supplies. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Dielectric Isolation (DI) processing for enhanced reliability and performance with extremely low static errors
- Built-in digital address decoding and enable input for simplified system integration
- Low output leakage current typically rated at 0.1nA for optimum low-level signal handling
- DTL/TTL compatible address inputs allowing direct interface without pullup resistors
Applications
- Medical instrumentation systems
- Telemetry systems
- Microprocessor-based data acquisition systems
- Precision instrumentation applications
- Demultiplexing and selector switch circuits
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific ordering suffix matches the required package type and temperature rating. Review the latest datasheet revision for any updates to absolute maximum ratings or electrical characteristics prior to finalizing procurement orders.
Selection Notes
Select this component when a single-ended 8-channel configuration is required with DTL/TTL logic compatibility. Ensure the application voltage does not exceed the ±15V supply limit and that the operating environment falls within the specified -55°C to +125°C range. Consider the 500Ω maximum ON resistance for current mode applications.
Part Context
The HI1-1818A belongs to the HI-18xx series of monolithic CMOS analog multiplexers produced by Intersil, now part of Renesas Electronics. This family utilizes Dielectric Isolation technology to achieve superior performance compared to conventional junction-isolated CMOS devices. The HI1-1818A specifically provides an 8-channel single-ended architecture suitable for general-purpose switching tasks.
Replacement Considerations
The datasheet explicitly states 'NO RECOMMENDED REPLACEMENT' and advises against new designs. No public substitute part numbers are documented in the source material.
