Product details
Overview
HI3-0547-5 from Intersil is an 8-channel differential analog multiplexer with active overvoltage protection, ±15V analog signal range, 70VP-P fault tolerance, and guaranteed rON matching. It operates across 0°C to 75°C in a 28-lead PDIP package and is used in industrial data acquisition systems where external analog sources may exceed supply rails.
For engineers reviewing the HI3-0547-5 datasheet, HI3-0547-5 pinout, HI3-0547-5 application, or HI3-0547-5 equivalent, this page delivers verified specifications, differential channel routing details, break-before-make timing, overvoltage leakage behavior under ±33V fault, and RoHS-compliant Pb-free packaging for through-hole wave soldering.
Technical Context
The HI3-0547-5 implements dielectrically isolated CMOS (CMOS-DI) technology with dedicated overvoltage clamp circuitry on each input pair, enabling continuous 70VP-P analog input tolerance while maintaining signal integrity during faults. Its decoder/driver architecture supports 3-bit address decoding (A2–A0) for selecting one of eight differential channel pairs without interaction between unselected paths.
Each channel features matched on-resistance (ΔrON ≤ 7.0%), 50 dB off-isolation at 100 kHz, and 30 pF channel output capacitance. The device uses level-shifted TTL/CMOS-compatible digital inputs and includes internal 1 kΩ fault-current limiting resistors when supplies are lost.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | 8 differential pairs (IN1A/IN1B through IN8A/IN8B) - enables simultaneous high-fidelity routing of balanced signals. |
| Overvoltage Protection | ±33V continuous analog overvoltage (70VP-P) - protects against transients from externally powered sensors without latch-up or damage. |
| rON Matching | ΔrON ≤ 7.0% (typical) - ensures consistent gain and minimal crosstalk in precision measurement front-ends. |
| Access Time | 500 ns typical - supports sampling rates up to ~1 MHz in multiplexed ADC architectures. |
| Power Dissipation | 7.5 mW typical at ±15V - enables low-thermal-drift operation in dense industrial PCB layouts. |
| Digital Interface | TTL/CMOS-compatible A0–A2 and EN inputs - eliminates need for level-shifting logic in microcontroller-driven systems. |
| Supply Range | ±15V max (44V total V+ to V−) - accommodates wide industrial signal ranges while preserving headroom for protection circuitry. |
Pinout & Package
HI3-0547-5 is supplied in a 28-lead plastic dual-in-line package (PDIP), Pb-free, rated for 0°C to 75°C operation. Lead finish is 100% matte tin; intended for wave solder only (not reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 28 | +VSUPPLY, −VSUPPLY | Primary analog power rails - must be decoupled locally to maintain noise immunity and overvoltage clamp performance. |
| 2, 3, 26, 27 | NC, NC, OUT B, OUT A | No-connect pins and differential outputs - OUT A/B drive complementary signal paths; NCs isolate internal die structures. |
| 4–11, 14–21 | IN1B–IN8B, IN1A–IN8A | Differential analog inputs - each pair (e.g., IN1A/IN1B) forms one selectable channel; all tolerate ±33V faults independently. |
| 12, 13, 15, 16 | GND, VREF, NC, ENABLE | Ground reference, open-voltage reference node, unused terminal, and master channel enable - EN must be high for any channel selection. |
| 17–19 | A0, A1, A2 | 3-bit binary address inputs - select one of eight differential channels (000 = CH1, 111 = CH8); no A3 line (unlike HI-546). |
Key Features
| Feature | Design Value |
|---|---|
| Active overvoltage protection | Clamps ±33V analog faults without degradation - maintains <100 nA off-leakage and preserves channel isolation during sustained overvoltage events. |
| Break-before-make switching | 80 ns minimum tOPEN - prevents momentary shorting between differential channel pairs during address transitions. |
| Guaranteed rON matching | ≤7.0% ΔrON across all 8 channels - enables accurate ratio-metric measurements in multi-sensor systems without per-channel calibration. |
| Differential channel architecture | Independent INxA/INxB pairs with common-mode rejection - suppresses noise in long-line sensor interfaces (e.g., strain gauges, RTDs). |
| Fault-tolerant digital interface | Digital inputs withstand (V−) −4V to (V+) +4V - allows direct connection to ±12V control logic or isolated gate drivers without buffering. |
Applications
| Data Acquisition Systems | Industrial Process Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI4P0547-5Z | Same die, 28-lead PLCC package (N28.45), identical electrical specs and temperature range (0°C to 75°C). | Surface-mount assembly required; higher thermal resistance (θJA = 70°C/W vs. 60°C/W for PDIP). | Select HI4P0547-5Z for space-constrained PCBs requiring SMT placement and reflow compatibility. |
| HI9P0547-9Z | Same functionality, 28-lead SOIC package (M28.3), extended temperature range (−40°C to +85°C), same Pb-free finish. | Wider operating envelope suits automotive or outdoor industrial enclosures; lower power dissipation due to smaller die attach area. | Choose HI9P0547-9Z when ambient temperature exceeds 75°C or board real estate demands gull-wing leads. |
Compared with HI4P0547-5Z and HI9P0547-9Z, the HI3-0547-5 offers lowest thermal resistance in through-hole form, simplifies wave solder process validation, and provides mechanical robustness for high-vibration environments - making it optimal for legacy industrial control hardware upgrades.

FAQ
What is the maximum analog overvoltage the HI3-0547-5 can sustain continuously?
The HI3-0547-5 sustains ±33V continuous analog overvoltage (70VP-P) on any input pair while maintaining signal integrity and sub-100 nA off-leakage. This rating applies with ±15V supplies and is validated per FN3150 Rev 7.00 Figure 3A. The HI3-0547-5 achieves this via integrated clamp diodes and 1 kΩ series current-limiting resistors per input path.
Does the HI3-0547-5 require external pull-up resistors on its digital inputs?
No, the HI3-0547-5 does not require external pull-ups on A0–A2 or ENABLE. Its digital inputs are TTL/CMOS-compatible with VAL = 0.8V and VAH = 4.0V thresholds. Pull-ups are only recommended when driving from DTL/TTL circuits lacking sufficient high-level drive - in which case 1 kΩ to +5V is specified in FN3150 Note 8. The HI3-0547-5 functions correctly with standard microcontroller GPIO outputs.
How does the HI3-0547-5 differ from the HI-546 family in pin compatibility?
The HI3-0547-5 is not pin-compatible with the HI-546. While both use 28-pin PDIP packages, the HI-546 has A3 addressing and 16 single-ended inputs, whereas the HI3-0547-5 omits A3 and routes eight differential pairs (IN1A/IN1B through IN8A/IN8B). Pin 2 is NC on HI3-0547-5 but IN16 on HI-546; pin 28 is −VSUPPLY on both, but output and address pin assignments differ fundamentally. Interchange requires PCB redesign.
Is the HI3-0547-5 suitable for reflow soldering processes?
No, the HI3-0547-5 is not suitable for reflow soldering. Its Pb-free PDIP package (E28.6) is qualified only for through-hole wave solder processing, as explicitly stated in FN3150 Rev 7.00 Page 2 footnote *. Reflow exposes the plastic body to temperatures exceeding its thermal limits and risks delamination or lead finish degradation. For reflow-compatible alternatives, consider HI9P0547-9Z (SOIC) or HI4P0547-5Z (PLCC).
What is the guaranteed rON matching specification for the HI3-0547-5 across temperature?
The HI3-0547-5 guarantees ΔrON ≤ 7.0% across all eight differential channels at 25°C, per FN3150 Rev 7.00 Page 9 Electrical Specifications table. This matching holds over the full 0°C to 75°C operating range, with rON itself varying from 1.5 kΩ (min) to 2.0 kΩ (max) - ensuring consistent channel gain in precision measurement applications without per-channel trimming. The HI3-0547-5 achieves this via matched transistor sizing and dielectric isolation.
