Product details
Overview
HI3-0509A-5 from Intersil is a differential 4-channel CMOS analog multiplexer with active overvoltage protection, designed for fault-tolerant signal routing in industrial and telemetry systems. It supports ±15V analog signal range, 70VP-P overvoltage tolerance, 500ns access time, and operates from 0°C to +75°C in a 16-lead PDIP package.
For engineers reviewing the HI3-0509A-5 datasheet, HI3-0509A-5 pinout, HI3-0509A-5 application, or HI3-0509A-5 equivalent, key selection criteria include differential channel count, break-before-make switching, fail-safe behavior during supply loss, and compatibility with ±15V rail systems requiring robust external input protection.
Technical Context
The HI3-0509A-5 implements dielectrically isolated CMOS (CMOS-DI) technology with dedicated overvoltage clamp circuitry that maintains signal isolation and prevents channel interaction during ±33V analog faults. Its decoder-driven address logic accepts A1/A0 inputs and an enable signal to select one of four differential channel pairs.
Each channel features 1kΩ fail-safe resistance when supplies are lost, and digital inputs tolerate continuous faults up to 4V beyond either supply rail. The device uses level-shifted TTL-compatible control inputs referenced to VREF and includes internal protection diodes and current-limiting structures per I/O path.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI1-0509A-5 | CERDIP package, -55°C to +125°C operating range, same pinout and electrical specs | Suitable for aerospace, military, or extended-temperature industrial deployments | Select HI1-0509A-5 when extended temperature range or hermetic packaging is required; HI3-0509A-5 preferred for commercial cost-sensitive designs |

FAQ
What is the maximum analog overvoltage the HI3-0509A-5 can withstand without damage?
The HI3-0509A-5 withstands continuous ±33V analog overvoltage relative to its supplies while maintaining channel isolation and signal path integrity. This is verified per datasheet Figure 3 and Absolute Maximum Ratings table. The device clamps faults internally without requiring external components, and this rating applies directly to the HI3-0509A-5 under its specified ±15V supply conditions.
Does the HI3-0509A-5 support break-before-make switching, and how is it implemented?
Yes, the HI3-0509A-5 guarantees break-before-make switching via internal decoder timing control. As confirmed in the Truth Table on page 4 and Functional Diagram on page 5, the enable and address decoding logic ensures no overlap between channel conduction states during transitions. This eliminates signal shorting between differential inputs - a critical requirement for HI3-0509A-5 in multi-sensor monitoring applications.
What happens to the HI3-0509A-5 inputs if the power supplies are removed during operation?
When supplies are lost, the HI3-0509A-5 enters a fail-safe state where each analog input presents a defined 1kΩ resistance to ground, preventing floating nodes and eliminating latch-up risk. This behavior is explicitly documented in the datasheet introduction and Absolute Maximum Ratings section, and is intrinsic to the HI3-0509A-5's protection architecture - independent of external biasing.
Is the HI3-0509A-5 pin-compatible with other devices in the HI-506A/507A/508A/509A family?
No - the HI3-0509A-5 uses a 16-pin PDIP footprint specific to the HI-509A variant, differing from the 28-pin layouts of HI-506A/HI-507A and the 16-pin CERDIP of HI1-0509A-5. While logic function and pin functions align within the HI-509A group (e.g., HI3-0509A-5 and HI1-0509A-5 share identical pin assignments), cross-family pin compatibility does not exist due to differing channel counts and address bus widths.
What is the typical on-resistance of the HI3-0509A-5, and how does it vary with signal voltage?
The HI3-0509A-5 exhibits a typical on-resistance of 1.5 kΩ at ±15V supplies and 25°C, with a maximum of 2.0 kΩ across the full 0°C to +75°C range. As shown in Figure 1B of the datasheet, rON remains stable across the ±10V analog input range, deviating less than ±5% - a key specification enabling precision gain-setting in HI3-0509A-5-based instrumentation front-ends.
