The device supports dual supply voltages ranging from ±15V to ±15V, with a maximum on-state resistance of 1.8 kOhms. It operates within an industrial temperature range of -40°C to +85°C and includes analog overvoltage protection rated at 70VP-P. Key electrical parameters include a maximum power dissipation of 7.5 mW and a maximum supply current of 2 mA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates analog overvoltage protection to prevent channel interaction during voltage spikes up to 70VP-P
• Utilizes break-before-make switching architecture to ensure signal integrity during transitions
• Supports dual supply operation for flexible system integration

Analog Switches, Multiplexers, Demultiplexers Applications

• Industrial process control systems requiring isolated signal routing
• Data acquisition systems with high-voltage input channels
• Test and measurement equipment needing robust analog switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix '9Z' corresponds to the RoHS-compliant lead-free variant as defined in the official Renesas datasheet. Confirm that the 28-SOIC package dimensions match your PCB footprint requirements. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range to maintain performance specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single 16:1 analog switch with integrated overvoltage protection is required. It is suitable for applications where channel isolation during overvoltage events is critical. Consider the 1.8 kOhm on-resistance and 300 ns switching times against system speed and accuracy requirements. Compare with the HI9P0547 series if differential or lower channel count configurations are needed instead.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HI-547 family of CMOS analog multiplexers. It serves as a specialized solution for high-voltage environments where standard switches might fail due to overvoltage conditions. The device complements other members of the family like the HI9P0547, offering distinct 16:1 topology versus differential options.
