HI4P0546-5Z

Analog Switches, Multiplexers, Demultiplexers Overview

The HI4P0546-5Z is a multiplexer switch IC manufactured by Renesas Electronics Corporation, formerly Intersil. It features an 8:1 single-ended configuration housed in a 28-pin PLCC package. The device supports dual power supplies with a maximum voltage of 22 V and operates within a temperature range of 0°C to +75°C. Key electrical parameters include a maximum on-resistance of 1.8 kOhms, a maximum operating time of 300 ns, and a maximum quiescent current of 2 mA. The component is designated as End-of-Life (EOL) and is no longer in active production.

• Utilizes annealed silicon technology for enhanced reliability

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in test and measurement equipment
• Data acquisition systems requiring analog switching
• Industrial control signal multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This component is officially classified as End-of-Life (EOL) by the manufacturer. Availability is restricted to remaining stock from authorized distributors or secondary market sources. Buyers should verify part authenticity and storage conditions carefully due to the discontinued status. Lead times are not applicable as standard supply has ceased.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Designers requiring this specific 8:1 multiplexer function must consider obsolescence risks when planning long-term production. While the HI4P0546-5Z offers specific OVP and annealing characteristics, alternative modern multiplexers may require schematic modifications. Evaluate pin compatibility and electrical parameter margins if substituting with newer generation switches from the same or other manufacturers.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HI4P0546-5Z belongs to the HI4P05xx series of multiplexer switches. This series typically includes variants such as the HI4P0547-5Z (differential 8:1) and HI4P0506-5Z (16:1). These components share similar packaging and basic operational principles but differ in channel count and signal type (single-ended vs. differential). The -5Z suffix indicates the lead-free and RoHS-compliant version of the package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific obsolete model. Engineers should consult Renesas technical support for recommended modern equivalents that match the 28-PLCC footprint and 8:1 single-ended switching requirements.
