Product details
Overview
HI1-0547-5 from Intersil is an 8-channel differential CMOS 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 and is fabricated in 44V dielectrically isolated CMOS technology for robustness in mixed-supply industrial data acquisition systems.
For engineers reviewing the HI1-0547-5 datasheet, HI1-0547-5 pinout, HI1-0547-5 application, or HI1-0547-5 equivalent, key selection criteria include differential channel count, break-before-make switching, ±15V rail-to-rail analog handling, 500ns typical access time, and 7.5mW standby power - all critical for fault-tolerant telemetry and industrial control interfaces.
Technical Context
The HI1-0547-5 implements a dual 4-channel differential architecture with independent A/B input pairs per selected channel, enabling true differential signal routing without common-mode coupling. Its active overvoltage protection clamps inputs up to ±33V while maintaining 1kΩ fault resistance and isolating undamaged channels during overvoltage events.
Address decoding uses three digital inputs (A0–A2) with enable control to select one of eight differential pairs; internal level shifters support TTL/DTL logic drive, and the 5V reference circuit ensures consistent switching thresholds regardless of supply voltage variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | 8 differential pairs (16 total inputs), supporting true differential signal routing |
| Analog Signal Range | ±15V - enables direct interface with industrial sensors and ±12V/±15V op-amp stages |
| Overvoltage Tolerance | 70VP-P continuous - protects against transients from external equipment or miswired sources |
| Access Time | 500ns typical - supports high-speed scanning in data acquisition at ≥1 MHz channel rate |
| On Resistance | 1.2–1.8 kΩ (25°C) with ≤7% matching - ensures minimal gain error and channel-to-channel crosstalk in precision measurement |
| Standby Power | 7.5mW typical - reduces thermal load in always-on industrial monitoring systems |
| Break-Before-Make | 80ns minimum delay - prevents momentary shorting between differential channel pairs during switching |
Pinout & Package
HI1-0547-5 is supplied in a 28-lead PDIP package (Pb-free, E28.6 outline), with 0°C to 75°C operating temperature range. The package features through-hole mounting compatibility and wave-solder process suitability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +VSUPPLY | Positive analog supply | Accepts +15V; powers analog switch core and protection circuitry |
| -VSUPPLY | Negative analog supply | Accepts -15V; defines lower rail for bipolar analog signal handling |
| GND | Analog ground reference | Return path for VREF and internal bias networks; separate from digital ground |
| VREF | Logic reference input | Configures level shifter threshold; open or tied to logic high for TTL compatibility |
| ENABLE | Channel enable control | Active-high; disables all switches when low, reducing leakage and power |
| A0–A2 | Binary address inputs | Select one of eight differential channel pairs (000 = CH1, 111 = CH8) |
| IN 1A–IN 8A | Differential input A side | Eight dedicated positive-side inputs for each differential pair |
| IN 1B–IN 8B | Differential input B side | Eight dedicated negative-side inputs; routed simultaneously with corresponding A input |
| OUT A / OUT B | Differential outputs | Paired outputs deliver selected differential signal to downstream instrumentation amplifier or ADC driver |
Key Features
| Feature | Design Value |
|---|---|
| Active overvoltage protection | Maintains signal integrity and prevents latch-up when analog inputs exceed ±15V rails by up to ±33V |
| No channel interaction during fault | Unselected channels remain fully isolated - no signal corruption or cross-talk under overvoltage conditions |
| Guaranteed rON matching | ≤7% max mismatch between any two channels ensures consistent gain and offset in multi-channel calibration |
| Break-before-make switching | Prevents momentary short-circuit between differential pairs during address transitions, avoiding transient spikes |
| 44V maximum supply rating | Supports extended rail operation (e.g., ±22V) for specialized high-dynamic-range front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential 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 temp range; Pb-free plus anneal finish | Better suited for surface-mount production and extended industrial temperature operation | Select HI9P0547-9Z when board space is constrained or reflow soldering is required |
| ADG508F | 8-channel single-ended (not differential); ±15V rating; integrated fault protection; higher 45Ω rON; no rON matching spec | Requires external differential amplification; less suitable for direct differential sensor routing | Choose ADG508F only if single-ended topology suffices and fault protection must be integrated with lower on-resistance |
Compared with HI1-0547-5, HI9P0547-9Z offers identical switching performance in a modern surface-mount package with wider temperature range, while ADG508F trades differential capability for lower rON and integrated fault protection - making HI1-0547-5 uniquely suited for precision differential multiplexing where channel matching and true differential routing are mandatory.

FAQ
What is the maximum analog overvoltage the HI1-0547-5 can withstand without damage?
The HI1-0547-5 can withstand continuous analog overvoltage up to ±33V beyond its ±15V supplies (i.e., 70VP-P), with active protection circuitry limiting input current and isolating unaffected channels. This is verified per datasheet Figure 3 and Absolute Maximum Ratings table, ensuring survivability in scenarios like sensor disconnects or miswired field connections.
Does the HI1-0547-5 support TTL-level digital control inputs?
Yes, the HI1-0547-5 supports TTL-level inputs: logic high threshold is 4.0V (min), logic low is 0.8V (max), and internal level shifters ensure reliable operation even with marginal drive strength. The VREF pin may be left open for standard TTL compatibility, as confirmed in Electrical Specifications Table and Application Note AN520.
What is the guaranteed on-resistance matching specification for the HI1-0547-5?
The HI1-0547-5 guarantees ΔrON ≤ 7.0% between any two channels at 25°C, as specified in the Electrical Specifications table under "ΔrON, (Any Two Channels)". This matching holds across the full operating temperature range and is critical for minimizing gain error in multi-channel precision measurement systems using HI1-0547-5.
Can the HI1-0547-5 operate with supplies other than ±15V?
Yes, the HI1-0547-5 supports supplies from ±5V up to ±22V (V+ to GND ≤ +22V, V− to GND ≥ −25V), with analog signal range scaling accordingly. Datasheet Figure 1C shows normalized rON vs supply voltage, and Absolute Maximum Ratings confirm 44V total V+–V− rating - enabling use in ±12V, ±10V, or asymmetric supply configurations with HI1-0547-5.
Is the HI1-0547-5 pin-compatible with other members of the HI-54x family?
No - the HI1-0547-5 has a unique 28-pin PDIP pinout optimized for its 8 differential channel architecture (e.g., separate INxA/INxB banks and dual outputs), differing from HI-546 (16-channel single-ended), HI-548 (8-channel single-ended), and HI-549 (4-channel differential). Pin compatibility is not claimed in the datasheet, and functional diagrams confirm distinct internal routing for HI1-0547-5.
