Product details
Overview
HI3-0546-5Z from Intersil is a single 16-channel CMOS analog multiplexer with active overvoltage protection, ±15V analog signal range, 70VP-P fault tolerance, guaranteed rON matching (±7%), and break-before-make switching. It serves as a high-reliability signal routing device in industrial data acquisition systems interfacing externally powered sensors.
For engineers reviewing the HI3-0546-5Z datasheet, HI3-0546-5Z pinout, HI3-0546-5Z application, or HI3-0546-5Z equivalent, key selection considerations include its 28-pin PDIP package, -40°C to +85°C operating range, 1.5 kΩ typical on-resistance, 500 ns access time, and differential fault isolation under ±33V overvoltage conditions.
Technical Context
The HI3-0546-5Z implements dielectrically isolated CMOS (CMOS-DI) technology with integrated overvoltage clamping circuitry that maintains signal fidelity during ±33V analog faults. Its decoder/driver architecture supports 4-bit address decoding (A0–A3) and enables channel selection without interaction between active and inactive paths.
Each analog input presents 1 kΩ resistance during supply loss, protecting external sources from short circuits. The device uses level-shifted TTL/CMOS-compatible digital inputs (0.8 V / 4.0 V thresholds) and features a dedicated VREF pin for logic-level adaptation up to 6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | 16 single-ended inputs, 1 common output - enables consolidated sensor multiplexing in compact DAQ front-ends |
| Overvoltage Protection | ±33V continuous analog overvoltage - prevents latch-up or damage when interfacing with unregulated or miswired field equipment |
| On Resistance (rON) | 1.5 kΩ typical at ±15V supplies - ensures minimal gain error and thermal drift in precision measurement paths |
| Access Time | 500 ns typical - supports sampling rates up to ~1 MHz in time-critical control loops |
| Supply Range | ±15V max (44V total), -25V to +22V relative to GND - accommodates dual-rail industrial power domains |
| Standby Power | 7.5 mW typical - reduces thermal load in sealed enclosures and battery-backed instrumentation |
| Channel Matching (ΔrON) | ≤7% max - preserves amplitude consistency across channels in multi-sensor calibration routines |
Pinout & Package
HI3-0546-5Z is housed in a 28-lead plastic dual-in-line package (PDIP), Pb-free compliant per RoHS, rated for 0°C to +75°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 27 | +VSUPPLY / -VSUPPLY | Primary dual-rail analog supply pins - must be decoupled locally to suppress crosstalk during switching transients |
| 14, 18 | GND / VREF | Ground reference and logic-level reference - VREF sets high-threshold for address/enable inputs above 4 V |
| 2, 3, 26 | NC | No-connect pins - left floating per datasheet; no internal connection or function |
| 4–13, 15–17, 19–25 | IN 1–IN 16 | Analog input terminals - each withstands ±20V continuous and ±33V fault voltage without degradation |
| 28 | OUT | Common analog output - routed to ADC input or instrumentation amplifier with <10 pF off-capacitance |
| 11, 12, 13, 20 | A0–A3 | 4-bit binary address inputs - select one of 16 channels; A3 is unused in HI-547/548/549 variants |
| 10 | ENABLE | Active-high channel enable - disables all switches and reduces leakage to <1 µA when low |
Key Features
| Feature | Design Value |
|---|---|
| Active Overvoltage Protection | Clamps ±33V analog faults while maintaining <4 nA off-leakage - eliminates need for external TVS diodes in sensor interface stages |
| No Channel Interaction | Isolated signal paths prevent fault propagation - critical when multiplexing mixed-voltage sensor banks (e.g., 0–5 V and ±10 V) |
| Break-Before-Make Switching | 80 ns minimum open delay - avoids momentary shorts during channel transitions in high-impedance source applications |
| Digital Input Fault Tolerance | Sustains +4 V beyond either supply rail - allows direct interfacing with 5 V microcontrollers even when analog rails are ±15 V |
| Guaranteed rON Matching | ≤7% variation across all 16 channels - enables accurate ratio-metric measurements without per-channel calibration |

FAQ
What is the maximum analog overvoltage rating for HI3-0546-5Z?
The HI3-0546-5Z supports continuous analog overvoltage of ±33V relative to its supply rails, verified per datasheet Note 4. This protection remains active even during supply loss, with each input presenting 1 kΩ resistance to limit current. The device sustains this stress without parameter shift or latch-up, making it suitable for interfacing with externally powered field instruments where wiring errors may occur.
Does HI3-0546-5Z require external pull-up resistors on address lines?
No, HI3-0546-5Z does not require external pull-ups on A0–A3 or ENABLE. Its digital inputs are TTL/CMOS compatible with defined thresholds (0.8 V low, 4.0 V high) and include internal level-shifting circuitry referenced to VREF. Pull-ups are only recommended when driving from DTL/TTL circuits with weak sourcing capability - a design choice, not a requirement for standard 5 V logic interfaces.
What is the guaranteed rON matching specification for HI3-0546-5Z?
The HI3-0546-5Z guarantees ΔrON ≤7% across any two channels at 25°C, as specified in the Electrical Specifications table on page 9 of FN3150 Rev 7.00. This matching holds under ±15V supplies and ±10V analog conditions, enabling precise ratio-metric measurements in multi-channel sensor arrays without per-channel gain correction.
Can HI3-0546-5Z operate with asymmetric supply voltages?
Yes, HI3-0546-5Z supports asymmetric supplies within absolute limits: V+ to GND ≤+22V, V− to GND ≥−25V, and V+ to V− ≤+44V. For example, +12V/−5V operation is valid if total differential remains ≤44V and individual rail-to-ground ratings are respected. Performance parameters like rON and leakage are characterized at ±15V but remain functional across the full safe operating area.
Is HI3-0546-5Z pin-compatible with other HI-546 variants?
Yes, HI3-0546-5Z shares identical pinout and function with all HI-546 variants (e.g., HI1-0546-2, HI9P0546-9Z, HI4P0546-5Z) across CERDIP, PDIP, SOIC, and PLCC packages. The 28-pin topology - including IN1–IN16, OUT, A0–A3, ENABLE, ±VSUPPLY, GND, and VREF - is consistent. Mechanical differences affect PCB layout, but electrical interface and firmware remain unchanged.
