Product details
Overview
HI3-0547-5Z 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 in 0°C to 75°C industrial temperature range and is packaged in 28-lead PDIP (Pb-free), serving as a robust signal routing solution for data acquisition systems interfacing external or separately powered sensors.
For engineers reviewing the HI3-0547-5Z datasheet, HI3-0547-5Z pinout, HI3-0547-5Z application, or HI3-0547-5Z equivalent, key selection criteria include differential channel count, ±15V rail-to-rail analog handling, break-before-make switching, 500ns typical access time, and 7.5mW standby power - all critical for fault-tolerant industrial signal conditioning designs.
Technical Context
The HI3-0547-5Z implements dielectrically isolated CMOS (CMOS-DI) technology with integrated overvoltage clamping circuitry that sustains ±33V analog overvoltage without damage or cross-channel interference. Its decoder/driver architecture supports 3-bit address decoding (A0–A2) for selecting one of eight differential input pairs (IN1A/IN1B through IN8A/IN8B) to dual outputs (OUT A / OUT B).
Each channel features matched on-resistance (ΔrON ≤ 7%), low off-leakage (≤200nA full temp range), and 1kΩ fault-protection impedance when supply loss occurs. The device uses level-shifted TTL-compatible digital inputs and includes VREF and GND pins for reference stability and noise isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | Differential 8-channel (4 pairs); enables simultaneous routing of complementary signals without common-mode degradation. |
| Analog Signal Range | ±15V; supports full-rail operation across industrial sensor outputs and instrumentation amplifiers. |
| Overvoltage Protection | 70VP-P continuous; protects against transient surges from external equipment without latch-up or signal path corruption. |
| Access Time | 500ns typical; ensures rapid channel switching for high-throughput data acquisition at ≥1MHz sampling rates. |
| On Resistance | 1.5kΩ typical (25°C); low and tightly matched (ΔrON ≤ 7%) for precision gain/attenuation accuracy in measurement paths. |
| Standby Power | 7.5mW typical; minimizes thermal load and self-heating drift in multi-mux systems. |
| Supply Voltage | ±15V max (44V total); accommodates wide dynamic range transducers while maintaining dielectric isolation integrity. |
Pinout & Package
HI3-0547-5Z is housed in a 28-lead plastic dual-in-line package (PDIP), Pb-free compliant per RoHS, suitable for wave soldering only. Package outline E28.6 defines 0.100" lead pitch, 1.380" × 0.600" body, and 0.115"–0.200" lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +V | Positive supply rail | Connects to +15V; powers internal logic and analog switches; must be decoupled locally. |
| -V | Negative supply rail | Connects to -15V; completes analog signal swing and bias network; requires separate decoupling. |
| GND | Analog/digital ground reference | Common return for VREF, enable, and address logic; isolate from noisy digital grounds to preserve SNR. |
| VREF | Reference voltage input | Open-circuit by default; used to set logic threshold for MOS-level drives; not required for TTL operation. |
| EN | Enable control input | Active-high; disables all channels when low (high-impedance state); synchronizes with address transitions. |
| A0–A2 | Channel select address inputs | 3-bit binary code selects one of eight differential pairs; TTL-compatible (0.8V/4.0V thresholds). |
| IN1A–IN8A | Differential input A side | Eight analog inputs forming positive legs of differential pairs; each withstands ±33V overvoltage independently. |
| IN1B–IN8B | Differential input B side | Eight analog inputs forming negative legs; matched to corresponding A-side channels for common-mode rejection. |
| OUT A / OUT B | Differential output terminals | Deliver selected differential pair; maintain signal fidelity under fault conditions due to active isolation circuitry. |
| NC | No-connect terminal | Pin 3 and Pin 13 are unconnected; must remain floating - no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Active overvoltage protection | Clamps ±33V faults without damage or channel crosstalk, enabling direct connection to field wiring without external protection diodes. |
| Guaranteed rON matching | ΔrON ≤ 7% between any two channels ensures consistent gain scaling across multiplexed sensor channels. |
| Break-before-make switching | Prevents momentary shorting between channels during address changes, eliminating signal glitches in precision measurement paths. |
| Differential 8-channel architecture | Supports true differential signal routing (e.g., thermocouple, bridge sensor outputs), preserving CMRR and rejecting ground-loop noise. |
| 44V dielectric isolation | CMOS-DI process prevents latch-up and leakage under high-voltage stress, ensuring reliability in harsh industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI9P0547-9Z | Same core functionality but in 28-lead SOIC package; -40°C to +85°C operating range; lower θJA (75°C/W) vs. PDIP (60°C/W). | Preferred for surface-mount production and extended temperature deployments; unsuitable for through-hole prototyping or wave-solder-only lines. | Select HI9P0547-9Z when board space is constrained and reflow capability exists; verify PCB land pattern matches M28.3 outline. |
| HI4P0547-5Z | Identical electrical specs and pinout; housed in 28-lead PLCC (N28.45); same 0°C to +75°C range; higher θJA (70°C/W). | Better mechanical ruggedness and thermal cycling performance than PDIP; requires socket or reflow-compatible footprint. | Choose HI4P0547-5Z for vibration-prone environments (e.g., transportation telemetry) where lead strength and coplanarity matter more than solder process compatibility. |
Compared with HI9P0547-9Z and HI4P0547-5Z, the HI3-0547-5Z offers wave-solder compatibility and legacy through-hole integration, while sacrificing thermal efficiency and mounting flexibility - making it optimal for cost-sensitive industrial control panels where manual assembly or wave soldering dominates.

FAQ
What is the maximum analog overvoltage the HI3-0547-5Z can sustain continuously?
The HI3-0547-5Z sustains ±33V analog overvoltage continuously, corresponding to a 70VP-P rating. This is verified under full temperature range (0°C to 75°C) with ±15V supplies and is enabled by its active clamp and isolation circuitry - not just passive diode limiting. The HI3-0547-5Z maintains signal path integrity and zero channel interaction during such faults.
Does the HI3-0547-5Z require external pull-up resistors on address or enable pins?
No, the HI3-0547-5Z does not require external pull-up resistors on A0–A2 or EN pins when driven by standard TTL sources (VAH = 4.0V, VAL = 0.8V). Its input thresholds are fully compatible with TTL logic levels. Pull-ups are only recommended if driving from DTL or open-collector sources, per Application Note AN520 - not applicable to typical microcontroller GPIO interfaces.
Can the HI3-0547-5Z operate with asymmetric supplies, such as +12V and -5V?
Yes, the HI3-0547-5Z supports asymmetric supplies as long as the total |+V – (–V)| ≤ 44V and each rail stays within absolute maximum ratings: +V to GND ≤ +22V, –V to GND ≥ –25V. For example, +12V/–5V yields 17V differential - well within spec - and preserves full ±15V analog signal swing capability relative to local GND.
What is the purpose of the VREF pin on the HI3-0547-5Z, and should it be connected?
The VREF pin on the HI3-0547-5Z sets the logic high threshold for MOS-level digital inputs (used only in HI-546/HI-547 variants). When driven by TTL (4.0V high), VREF may be left open. Connecting VREF to a voltage >6V raises the VAH threshold accordingly. For standard TTL or MCU use, VREF remains unconnected - no external bias or termination is needed for HI3-0547-5Z operation.
Is the HI3-0547-5Z pin-compatible with other members of the HI-54x family, such as the HI3-0546-5Z?
No, the HI3-0547-5Z is not pin-compatible with HI3-0546-5Z. While both use 28-pin PDIP packages, their pinouts differ significantly: HI3-0546-5Z has A3–A0 addressing and single-ended 16-channel I/O, whereas HI3-0547-5Z omits A3, uses differential I/O pairs (IN1A/IN1B…IN8A/IN8B), and dedicates pins to OUT A/OUT B. Direct substitution would cause functional failure and potential damage.
