Product details
Overview
HI9P0548-9Z from Intersil is a single 8-channel CMOS analog multiplexer with active overvoltage protection, ±15V analog signal range, 70VP-P fault tolerance, and guaranteed rON matching. It operates from –40°C to +85°C in a 16-lead SOIC package and is used in industrial data acquisition systems where external sensor inputs may exceed supply rails.
For engineers reviewing the HI9P0548-9Z datasheet, HI9P0548-9Z pinout, HI9P0548-9Z application, or HI9P0548-9Z equivalent, key selection criteria include overvoltage robustness (±33V sustained), break-before-make switching, 25pF channel output capacitance, 1.5kΩ typical on-resistance, and compatibility with TTL/CMOS logic levels.
Technical Context
The HI9P0548-9Z implements dielectrically isolated CMOS (CMOS-DI) technology with integrated overvoltage clamp circuitry that isolates faulted channels without disturbing signal integrity on other paths. Its decoder/driver and level-shift architecture supports 3-bit address decoding (A0–A2) and enables single-channel selection via EN control.
Each analog input withstands continuous ±33V overvoltage relative to supplies while maintaining ≤4nA off-leakage under fault conditions. The device features 1kΩ input resistance during supply loss and guarantees ΔrON ≤7% across any two channels at ±15V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | Single 8-channel configuration - selects one of eight analog inputs to common output. |
| Analog Signal Range | ±15V - supports rail-to-rail operation with full linearity across industrial sensor voltage spans. |
| Overvoltage Protection | ±33V sustained - protects against transient faults without latch-up or degradation. |
| On Resistance (rON) | 1.5kΩ typical - ensures minimal gain error and thermal drift in precision measurement paths. |
| Channel Output Capacitance | 25pF - limits bandwidth impact and settling time in high-speed sampling applications. |
| Access Time | 500ns typical - enables sub-microsecond channel switching for real-time multiplexed ADC systems. |
| Break-Before-Make Delay | 80ns - prevents momentary shorting between channels during address transitions. |
| Operating Temperature | –40°C to +85°C - qualified for extended industrial environments without derating. |
Pinout & Package
HI9P0548-9Z is housed in a 16-lead SOIC package (JEDEC MS-013-AE, outline M16.15), surface-mount compatible with standard reflow profiles and RoHS-compliant matte tin termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Analog Inputs IN1–IN8 | High-impedance, overvoltage-protected signal inputs; each tolerates ±33V independent of supply state. |
| 9 | OUT | Common analog output node; routed to selected INx channel when enabled. |
| 10 | GND | Analog ground reference; decoupling required for noise-sensitive measurements. |
| 11 | +VSUPPLY | Positive analog supply rail; supports up to +22V relative to GND per absolute max rating. |
| 12 | A0 | LSB address input; TTL/CMOS-compatible, controls channel selection bit 0. |
| 13 | A1 | Address input bit 1; level-shifted internally to match analog domain timing. |
| 14 | A2 | MSB address input; completes 3-bit decode for 8-channel selection. |
| 15 | ENABLE | Active-high digital enable; disables all switches and reduces standby power to 7.5mW. |
| 16 | –VSUPPLY | Negative analog supply rail; supports down to –25V relative to GND per absolute max rating. |
Key Features
| Feature | Design Value |
|---|---|
| Active Overvoltage Protection | Clamps ±33V faults without signal path disturbance or damage - eliminates need for external TVS diodes. |
| Guaranteed rON Matching | ΔrON ≤7% across channels - ensures consistent gain and offset in multi-sensor calibration schemes. |
| Break-Before-Make Switching | 80ns minimum isolation gap - prevents cross-talk or short-circuits during channel transitions. |
| Digital Input Fault Tolerance | Sustains logic inputs up to 4V beyond either supply rail - accommodates mismatched logic families. |
| Low Off-Leakage Current | ≤50nA at full temperature range - preserves accuracy in high-impedance sensor interfaces (e.g., thermocouples). |
| Dielectric Isolation | CMOS-DI process - suppresses latch-up and substrate coupling in noisy 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 |
|---|---|---|---|
| HI9P0548-5Z | Same silicon, 0°C to +75°C temperature range; identical electrical specs and pinout. | Restricted to commercial-temperature environments; unsuitable for extended industrial deployment. | Select HI9P0548-5Z only if ambient operating temperature remains within 0–75°C and cost is prioritized over thermal margin. |
| ADG508AKRZ-REEL7 | No active overvoltage protection; max analog input = ±16.5V; rON matching not guaranteed. | Lacks fault resilience - requires external clamping for field-connected sensors. | Choose ADG508AKRZ-REEL7 only in benign lab environments where overvoltage risk is eliminated by system design. |
Compared with HI9P0548-5Z, the HI9P0548-9Z extends operational reliability to –40°C cold starts and +85°C cabinet temperatures; versus ADG508AKRZ-REEL7, it delivers intrinsic ±33V fault tolerance and guaranteed rON matching-critical for unattended industrial systems.

FAQ
What is the maximum analog overvoltage the HI9P0548-9Z can sustain continuously?
The HI9P0548-9Z sustains continuous ±33V analog overvoltage relative to its supply rails without damage or signal path disruption. This is verified per datasheet Note 4 and enables direct interfacing with externally powered field devices. The HI9P0548-9Z maintains ≤4nA off-leakage current under this condition, preserving measurement integrity across unselected channels.
Does the HI9P0548-9Z require an external VREF connection?
No, the HI9P0548-9Z operates with VREF pin left open, as confirmed in the Electrical Specifications table (test conditions specify "VREF Pin = Open"). Unlike some mux families, it does not rely on an external reference for level shifting or biasing-the internal 5V reference and level-shift circuitry function autonomously. This simplifies layout and reduces external component count for the HI9P0548-9Z.
What is the guaranteed rON matching specification for the HI9P0548-9Z?
The HI9P0548-9Z guarantees ΔrON ≤7.0% across any two channels at TA = 25°C, as specified in the Electrical Specifications table under "ΔrON, (Any Two Channels)". This matching holds across the full operating temperature range (–40°C to +85°C) and supports precision applications like multi-sensor calibration where channel-to-channel gain consistency is critical.
Can the HI9P0548-9Z be used with single-supply operation?
No-the HI9P0548-9Z requires dual ±15V supplies (or equivalent, up to ±22V/+22V per Absolute Maximum Ratings) to meet its specified analog signal range (±15V) and overvoltage protection performance. Single-supply operation is not supported; attempting it violates the V+ to V– limit of +44V and compromises overvoltage clamping functionality in the HI9P0548-9Z.
Is the HI9P0548-9Z pin-compatible with other members of the HI-548 family?
Yes-the HI9P0548-9Z shares identical pinout and footprint with HI9P0548-5Z and HI1-0548-2, as confirmed by the "HI-548 (CERDIP, PDIP, SOIC) TOP VIEW" diagram on page 3 and the ordering table on page 2 of FN3150 Rev 7.00. All HI-548 variants use the same 16-pin arrangement regardless of package or temperature grade, enabling drop-in replacement within the same package type.
