Product details
Overview
HI9P0548-5Z 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 0°C to 75°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 HI9P0548-5Z datasheet, HI9P0548-5Z pinout, HI9P0548-5Z application, or HI9P0548-5Z equivalent, key selection criteria include its break-before-make switching, 500ns typical access time, 25pF channel output capacitance, and robust ±33V overvoltage immunity on analog inputs without signal path disturbance.
Technical Context
The HI9P0548-5Z implements dielectrically isolated CMOS (CMOS-DI) technology with integrated overvoltage clamp and signal isolation circuitry. Its decoder/driver stage accepts three address lines (A0–A2) and an enable input to select one of eight analog channels to a common output.
Each analog input withstands continuous ±33V overvoltage relative to supplies while maintaining 1kΩ series resistance under fault conditions. Digital inputs tolerate faults up to 4V beyond either supply rail, and the device features TTL/CMOS-compatible logic thresholds with internal level shifting referenced to VREF.

FAQ
What is the maximum continuous overvoltage rating for HI9P0548-5Z analog inputs?
The HI9P0548-5Z analog inputs withstand continuous ±33V overvoltage relative to the supply rails. This is verified per datasheet Note 4 and enables direct connection to externally powered sensors or field wiring without external clamping. The device maintains signal path integrity and does not latch up or degrade under this stress condition.
Does HI9P0548-5Z require an external VREF connection?
No, HI9P0548-5Z operates with VREF pin left open. Internal level-shifting circuitry uses the digital supply rails to interpret TTL/CMOS logic levels. The datasheet specifies VAH = 4.0V and VAL = 0.8V under standard test conditions, and no external reference voltage is needed for normal operation of the HI9P0548-5Z.
What is the guaranteed rON matching specification for HI9P0548-5Z?
The HI9P0548-5Z 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 over the full operating temperature range (0°C to 75°C) and ensures consistent gain scaling in multi-channel measurement systems using the HI9P0548-5Z.
Can HI9P0548-5Z be used with single-supply operation?
No, HI9P0548-5Z requires dual ±15V supplies for full-spec operation, including ±15V analog signal range and ±33V overvoltage protection. The Absolute Maximum Ratings specify V+ to V− ≤ +44V and analog input limits of (V−) −20V to (V+) +20V. Single-supply use violates these constraints and is not supported for the HI9P0548-5Z.
Is HI9P0548-5Z compatible with standard SOIC-16 PCB footprints?
Yes, HI9P0548-5Z uses JEDEC MS-013-AE compliant SOIC-16 packaging (drawing M16.15) with 1.27mm pitch and gull-wing leads. Its land pattern matches industry-standard SOIC-16 footprints, and the device supports conventional reflow soldering per IPC/JEDEC J-STD-020 moisture sensitivity level requirements for the HI9P0548-5Z.
