HI3-0549-5Z

Overview

The HI3-0549-5Z is a differential 4-channel CMOS analog multiplexer featuring active overvoltage protection, manufactured by Intersil. It operates within a maximum power supply of 44V and supports analog inputs withstanding constant 70VP-P levels even with ±15V supplies. The device ensures signal fidelity during fault conditions without channel interaction or damage to the signal path. Digital inputs sustain continuous faults up to 4V greater than either supply. Fabricated using 44V dielectrically isolated CMOS technology, it provides fail-safe operation with power loss and prevents latch-up.

Feature Summary

Active overvoltage protection circuitry maintains signal fidelity under fault conditions
Analog inputs withstand 70VP-P levels without damaging the device or disturbing other channels
Fail-safe operation with no latch-up during power loss events

Applications

Systems where analog inputs originate from external equipment
Applications involving separately powered circuitry
Signal routing in environments prone to voltage transients

Part Context

The HI3-0549-5Z belongs to the HI-509A family of analog multiplexers. This family includes single-channel and differential variants (HI-506A, HI-507A, HI-508A) sharing similar overvoltage protection features. The HI-509A specifically offers a differential 4-channel configuration, distinguishing it from the 8-channel and 16-channel options in the series.

Replacement Considerations

For applications not requiring overvoltage protection, the standard HI-506, HI-507, HI-508, or HI-509 multiplexers are recommended alternatives. Refer to Application Note AN520 for detailed comparison and selection guidance between protected and unprotected variants.
