Product details
Overview
HI4P0547-5Z from Intersil is an 8-channel differential CMOS analog multiplexer with active overvoltage protection, ±15V analog signal range, 70VP-P fault tolerance, guaranteed rON matching (±7%), and break-before-make switching-designed for industrial data acquisition systems interfacing externally powered sensors.
For engineers reviewing the HI4P0547-5Z datasheet, HI4P0547-5Z pinout, HI4P0547-5Z application, or HI4P0547-5Z equivalent, key selection criteria include differential channel count, ±15V rail compatibility, 1.5kΩ typical on-resistance, 500ns typical access time, and PLCC-28 packaging for high-reliability mixed-signal routing.
Technical Context
The HI4P0547-5Z implements a dielectrically isolated CMOS (CMOS-DI) process with integrated overvoltage clamping circuitry that sustains ±33V analog overvoltage without damage or signal path disturbance. Its decoder/driver architecture supports 3-bit address decoding (A0–A2) to select one of eight differential input pairs (IN1A/IN1B through IN8A/IN8B) to dual outputs (OUT A/OUT B).
Each channel features matched rON tracking across temperature, 1kΩ fault-protection resistance when supply is lost, and level-shifted TTL/CMOS-compatible digital inputs referenced to VREF. The device operates from 0°C to +75°C with ±15V supplies and draws only 7.5mW standby power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | 8 differential pairs (IN1A/B to IN8A/B), enabling simultaneous bidirectional signal routing in balanced measurement paths |
| Overvoltage Protection | ±33V continuous analog overvoltage tolerance with <4nA off-leakage under fault-prevents latch-up and preserves channel isolation |
| rON Matching | ΔrON ≤ 7% between any two channels at ±10V, ensuring consistent gain and linearity in multi-channel instrumentation |
| Access Time | 500ns typical (1.0μs max), supporting 1 MSPS sampling in time-critical telemetry applications |
| Supply Range | ±15V (max ±22V/–25V), compatible with standard industrial op-amp rails and legacy control system power domains |
| Package | 28-lead PLCC (N28.45), surface-mountable with 0.490" × 0.490" footprint and gull-wing leads for reflow soldering |
| Power Dissipation | 7.5mW typical standby, reducing thermal load in densely packed I/O modules and embedded DAQ boards |
Pinout & Package
HI4P0547-5Z is housed in a 28-lead Plastic Leaded Chip Carrier (PLCC) package per JEDEC MS-018AB, with gull-wing leads, 0.050" pitch, and a 0.490" × 0.490" body size. Pin 1 is marked by a corner notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | OUT B / OUT A | Differential output terminals-drive complementary signals to downstream instrumentation amplifiers or ADC front-ends |
| 3 | NC | No-connect; internal die pad not bonded-must remain unconnected to avoid parasitic coupling |
| 4–11 | IN 8B–IN 1B | Negative-side inputs of 8 differential pairs-accept inverted sensor outputs, reference returns, or balanced transducer signals |
| 12–13 | +VSUPPLY / –VSUPPLY | Analog supply rails-require local ±15V decoupling (0.1μF ceramic + 10μF tantalum) to maintain overvoltage clamp integrity |
| 14–15 | IN 8A / GND | Positive-side inputs and ground reference-GND serves as logic and analog return; must be star-connected to minimize noise |
| 16–17 | VREF / NC | Reference voltage input for level-shifting digital inputs; NC pin isolates internal substrate bias node |
| 18–20 | A2 / A1 / ENABLE | Address decode bits and channel enable-ENABLE must be high to activate selected pair; all address lines TTL/CMOS compatible |
| 21–28 | A0 / IN 7A–IN 1A | LSB address and positive-side inputs-IN 1A–IN 7A complete the 8 differential input set; A0 selects LSB for 3-bit decoding |
Key Features
| Feature | Design Value |
|---|---|
| Active Overvoltage Protection | Sustains ±33V continuous analog overvoltage without degradation-enables direct connection to field wiring without external clamps |
| No Channel Interaction During Fault | Unselected channels remain fully isolated (<–68dB off-isolation) during overvoltage events-preserves integrity of parallel measurement paths |
| Guaranteed rON Matching | ≤7% ΔrON across all 8 channels ensures uniform gain scaling in multi-channel calibration and ratio-metric sensing |
| Break-Before-Make Switching | 80ns minimum break interval prevents momentary shorting between differential pairs-critical for avoiding transient errors in precision bridge measurements |
| Dielectric Isolation (CMOS-DI) | Eliminates latch-up risk and enables operation with floating grounds-supports isolated sensor interfaces in motor drives and PLC I/O modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI3-0547-5Z | Same die, 28-lead PDIP package (E28.6); no Pb-free anneal; 0°C to +75°C rating identical | Through-hole mounting only; unsuitable for SMT production; higher thermal resistance (θJA = 60°C/W vs. 70°C/W) | Select for prototyping or legacy through-hole designs where rework flexibility outweighs density constraints |
| HI9P0547-9Z | Same functionality, 28-lead SOIC package (M28.3); extended temp range (–40°C to +85°C); Pb-free plus anneal | Smaller footprint (0.71" × 0.29") but lower creepage/clearance; less robust against mechanical stress than PLCC | Select for commercial-grade applications requiring wider temperature margin and RoHS-compliant reflow assembly |
Compared with HI3-0547-5Z and HI9P0547-9Z, HI4P0547-5Z offers superior mechanical reliability in vibration-prone industrial enclosures due to its PLCC gull-wing leads and ceramic-filled body, while maintaining identical electrical performance and Pb-free compliance for modern SMT lines.

FAQ
What is the operating temperature range for HI4P0547-5Z?
The HI4P0547-5Z is rated for operation from 0°C to +75°C, as specified in the FN3150 Rev 7.00 datasheet. This commercial temperature grade aligns with its intended use in controlled-environment industrial electronics, including programmable logic controller I/O modules and benchtop test equipment where ambient heat is managed via enclosure design or forced air cooling. The device's CMOS-DI process ensures stable rON and leakage performance across this full range.
Does HI4P0547-5Z support single-supply operation?
No, HI4P0547-5Z requires dual ±15V supplies for full specification compliance. Its analog signal range is ±15V, overvoltage protection is defined relative to both rails, and internal level shifters depend on symmetric supply voltages. Operation with single-ended supplies (e.g., 0V and +30V) violates absolute maximum ratings and risks permanent damage to the overvoltage clamp circuitry. Designers must use dedicated ±15V regulators or isolated DC/DC converters.
What is the meaning of "No longer available" in the HI4P0547-5Z ordering note?
The "No longer available" designation indicates that Intersil (now Renesas) has discontinued active manufacturing of HI4P0547-5Z. However, Aetrix Electronics maintains verified, traceable inventory of genuine HI4P0547-5Z devices sourced from authorized channels, with full lot traceability and extended lifecycle support-including obsolescence forecasting, last-time buy coordination, and cross-reference guidance for migration paths.
How does the overvoltage protection in HI4P0547-5Z function during supply loss?
When either ±15V supply fails, HI4P0547-5Z's internal protection circuitry presents a 1kΩ resistance at each analog input terminal, preventing short circuits and limiting current to safe levels. This behavior-documented in the functional diagrams and absolute maximum ratings-is independent of digital control state and remains active even with ENABLE low. It safeguards connected sensors and upstream signal conditioning stages from damage due to back-driving or floating supply conditions.
Can HI4P0547-5Z be used with 3.3V logic-level microcontrollers?
Yes, HI4P0547-5Z accepts 3.3V logic inputs directly when VREF is left open or tied to 3.3V, as its digital inputs meet TTL thresholds (VAL ≤ 0.8V, VAH ≥ 4.0V). With VREF = open, the internal level shifter interprets 3.3V as valid high; no external level translation is needed. However, designers must ensure the microcontroller's 3.3V output can drive the 10pF+ capacitance of the A0–A2 and ENABLE pins without excessive rise/fall time degradation-verified via layout simulation or empirical testing.
