Product details
Overview
HI4P0547-5 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 from 0°C to 75°C in a 28-lead PLCC package and is used in industrial data acquisition systems where external sensor inputs may exceed supply rails.
For engineers reviewing the HI4P0547-5 datasheet, HI4P0547-5 pinout, HI4P0547-5 application, or HI4P0547-5 equivalent, key selection criteria include differential channel count, break-before-make switching, ±15V signal handling, 500ns typical access time, and 1.5kΩ typical on-resistance - all critical for high-reliability analog signal routing under fault conditions.
Technical Context
The HI4P0547-5 implements dielectrically isolated CMOS (CMOS-DI) technology with integrated overvoltage clamp circuitry that sustains ±33V analog overvoltage without damage or channel interaction. Its decoder/driver and level-shift architecture supports TTL/DTL logic inputs and maintains signal isolation during supply loss.
Each differential pair features matched rON (ΔrON ≤ 7%), 30pF channel output capacitance, and <100nA off-state leakage at full temperature range. The device uses a 3-bit address (A2–A0) and enable control to select one of eight differential input pairs to the dual outputs OUT A and OUT B.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
HI4P0547-5 is housed in a 28-lead Plastic Leaded Chip Carrier (PLCC) package per JEDEC MS-018AB, with gull-wing leads, 0.050" pitch, and body dimensions 0.485" × 0.485". Pin 1 is marked by a corner notch; the package is RoHS-compliant Pb-free plus anneal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +VSUPPLY | Positive analog supply rail - must be decoupled locally to maintain noise immunity during switching |
| 2 | OUT B | Negative-side output of selected differential pair - routed to instrumentation amplifier in- input |
| 3–4 | NC | No-connect pins - left unconnected per design; no internal function or bonding |
| 5–12 | IN 8B to IN 1B | Negative inputs of differential channels 8 through 1 - accept inverted signals from sensors or transformers |
| 13 | GND | Analog ground reference - serves as return path for bias currents and shields signal integrity |
| 14 | VREF | Reference voltage input for level-shifter - open-circuit default enables TTL-compatible logic thresholds |
| 15–16 | NC | No-connect pins - electrically isolated; no internal connection or parasitic coupling |
| 17 | OUT A | Positive-side output of selected differential pair - routed to instrumentation amplifier in+ input |
| 18 | -VSUPPLY | Negative analog supply rail - must be decoupled symmetrically with +VSUPPLY |
| 19–26 | IN 8A to IN 1A | Positive inputs of differential channels 8 through 1 - accept non-inverted signals from sensors or transformers |
| 27 | ENABLE | Active-high digital control - disables all switches when low, preventing unintended channel conduction |
| 28 | A0 | LSB address input - selects channel pair with A1 and A2; TTL/DTL compatible with 4V high threshold |
Key Features
| Feature | Design Value |
|---|---|
| Active Overvoltage Protection | Sustains ±33V analog overvoltage while limiting input current to 4nA - eliminates need for external clamping diodes in harsh EMI environments |
| Break-Before-Make Switching | 80ns minimum tOPEN - prevents momentary shorting between channels during address transitions, avoiding signal corruption |
| Guaranteed rON Matching | ≤7% ΔrON across any two channels - ensures consistent gain and common-mode rejection in differential measurements |
| Digital Input Fault Tolerance | Withstands logic inputs up to 4V beyond either supply - accommodates floating or mismatched controller I/O levels |
| Signal Isolation Under Supply Loss | Each input presents 1kΩ resistance when supplies are absent - prevents back-driving of external sensor circuits during power-down |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI3-0547-5Z | Same HI-547 functionality but in 28-lead PDIP package; no Pb-free anneal process; 0°C to 75°C operation | Through-hole mounting only; not suitable for surface-mount production or reflow soldering | Select HI3-0547-5Z only for prototyping or legacy wave-solder assembly where PLCC footprint is unavailable |
| HI9P0547-9Z | Same HI-547 core in 28-lead SOIC; extended -40°C to +85°C temp range; Pb-free plus anneal | Lower profile and smaller footprint than PLCC; higher θJA (75°C/W vs 70°C/W) requires careful thermal layout | Choose HI9P0547-9Z for space-constrained designs needing wider temperature coverage and SMT compatibility |

FAQ
What is the maximum analog overvoltage the HI4P0547-5 can withstand continuously?
The HI4P0547-5 can withstand continuous ±33V analog overvoltage relative to its supplies, corresponding to a 70VP-P rating. This is enabled by integrated active clamp circuitry that limits input current to 4nA under fault conditions, protecting both the device and downstream circuitry without external components.
Does the HI4P0547-5 support TTL-level digital control inputs?
Yes, the HI4P0547-5 supports TTL-level digital inputs: logic high threshold (VAH) is 4.0V, and logic low threshold (VAL) is 0.8V, with input leakage ≤1.0μA. When VREF is left open, the internal level shifter ensures compatibility with standard 5V TTL and DTL logic families without pull-up resistors.
What is the guaranteed rON matching specification for the HI4P0547-5?
The HI4P0547-5 guarantees ΔrON ≤ 7% between any two channels at 25°C, measured with VOUT = ±10V and IOUT = 100μA. This tight matching ensures consistent gain and common-mode rejection ratio (CMRR) across all eight differential pairs in precision measurement applications.
Can the HI4P0547-5 operate with supplies other than ±15V?
Yes, the HI4P0547-5 operates with supplies ranging from ±5V to ±15V, with absolute maximum ratings of +22V (V+ to GND) and –25V (V– to GND). Its on-resistance and leakage specs are characterized at ±15V, but functional operation is maintained across the full ±5V to ±15V range, including asymmetric supplies such as +12V/–5V.
Is the HI4P0547-5 pinout compatible with other HI-547 variants like HI3-0547-5Z?
Yes, the HI4P0547-5 shares identical pinout and electrical functionality with all HI-547 family members including HI3-0547-5Z and HI9P0547-9Z. All variants use the same 28-pin assignment for +VSUPPLY, differential inputs (IN xA/IN xB), outputs (OUT A/OUT B), address lines (A0–A2), ENABLE, and GND/VREF, enabling direct PCB footprint reuse across package types.
