Product details
Overview
HI4P0548-5 from Intersil is a single 8-channel CMOS analog multiplexer with active overvoltage protection, ±15V analog signal range, 1.5 kΩ typical on-resistance, 500 ns typical access time, and break-before-make switching. It serves as a fault-tolerant signal routing device in data acquisition systems interfacing external sensors or separately powered instrumentation.
For engineers reviewing the HI4P0548-5 datasheet, HI4P0548-5 pinout, HI4P0548-5 application, or HI4P0548-5 equivalent, key selection criteria include guaranteed rON matching across channels, 70 VP-P analog overvoltage tolerance, 16-pin SOIC packaging, and compatibility with ±15V dual-supply industrial signal chains.
Technical Context
The HI4P0548-5 implements dielectrically isolated CMOS (CMOS-DI) technology to enable robust analog channel isolation under fault conditions. Its overvoltage protection circuitry clamps inputs up to ±33V without damaging the device or disturbing other channels, while maintaining signal fidelity via 1 kΩ input resistance during supply loss.
It uses a 3-bit address decoder (A0–A2) with enable control to select one of eight analog inputs to a common output. The internal level shifter supports TTL/DTL logic drive, and the functional diagram confirms dedicated overvoltage clamp and signal isolation blocks per channel.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI9P0548-5Z | Same 8-channel function and SOIC-16 package; rated for -40°C to +85°C operating range vs. HI4P0548-5's 0°C to +75°C | Preferred for extended-temperature deployments such as outdoor telemetry or automotive under-hood modules | Select HI9P0548-5Z when ambient operating temperature exceeds 75°C or drops below 0°C |
| ADG508AKRZ-REEL7 | 8-channel CMOS mux with ±15 V analog range but no active overvoltage protection; 400 Ω rON, 250 ns access time | Lacks fault tolerance for ±33 V transients; requires external protection circuitry in harsh environments | Choose ADG508AKRZ-REEL7 only in benign lab or controlled indoor settings where overvoltage risk is negligible |
Compared with HI9P0548-5Z, HI4P0548-5 offers lower cost and tighter thermal qualification for commercial-grade industrial use; compared with ADG508AKRZ-REEL7, it delivers critical overvoltage resilience at the expense of higher rON and slower switching-making it indispensable in unconditioned field deployments.

FAQ
What is the maximum analog overvoltage the HI4P0548-5 can withstand without damage?
The HI4P0548-5 can withstand continuous analog overvoltage of ±33 V (70 VP-P) while maintaining signal path integrity and preventing damage to internal circuitry. This capability is enabled by integrated active clamping and isolation structures, verified per datasheet Figure 3A and Absolute Maximum Ratings table.
Does the HI4P0548-5 require external pull-up resistors on its address lines?
No, the HI4P0548-5 does not require external pull-up resistors on A0–A2 or ENABLE. Its input threshold is TTL-compatible (VAL = 0.8 V, VAH = 4.0 V), and internal level-shifting circuitry accepts direct microcontroller GPIO drive. Pull-ups are only recommended for DTL/TTLCircuits per Note 8 in the datasheet.
What is the guaranteed rON matching specification for the HI4P0548-5?
The HI4P0548-5 guarantees ΔrON ≤ 7.0% between any two channels at 25°C, as specified in the Electrical Specifications table on page 9 of FN3150 Rev 7.00. This matching holds across the full ±15 V analog range and supports precision gain calibration in multi-channel systems.
Can the HI4P0548-5 operate with a single +5 V supply?
No, the HI4P0548-5 requires dual ±15 V supplies for full-specification operation. Its Absolute Maximum Ratings limit V+ to +22 V and V− to −25 V relative to GND, and analog signal range is specified only for ±15 V. Single-supply operation is not supported or characterized.
Is the HI4P0548-5 RoHS compliant and Pb-free?
Yes, the HI4P0548-5 is Pb-free plus anneal (RoHS compliant), using 100% matte tin plate termination finish and RoHS-compliant molding compounds and die attach materials, as confirmed in the Ordering Information section and Notes on page 2 of FN3150 Rev 7.00.
