HI9P0508-5

Analog Switches, Multiplexers, Demultiplexers Overview

The HI9P0508-5 is an analog multiplexer manufactured by Renesas Electronics Corporation, formerly Harris. It features a single 8:1 channel configuration housed in a 16-pin PDSO package. The device operates with a nominal dual supply voltage of ±15 V and supports a maximum ON resistance of 400 Ω. Key electrical specifications include a typical off-isolation of 68 dB and an on-resistance matching specification of 9 Ω. The component is designed for operation within a temperature range of -55 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High isolation performance for signal integrity
• Low on-resistance variation across channels

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems
• Industrial process control
• Test and measurement equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as this component was originally produced by Harris Semiconductor before its acquisition by Intersil and subsequently Renesas. Confirm the specific suffix '-5' denotes the extended industrial temperature grade (-55°C to +125°C) rather than the commercial grade. Ensure the datasheet version aligns with the current Renesas product line documentation to avoid discrepancies in pinout or electrical limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the HI9P0508-5 when a single-ended 8-to-1 multiplexing function is required with high channel isolation. Compare the 400 Ω maximum on-resistance against system signal loss requirements. Verify that the ±15 V dual supply capability matches the available power rails in the design. Consider the 16-pin SOIC package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the HI9P series of analog switches and multiplexers. It represents legacy technology from the Harris Semiconductor portfolio, now maintained under the Renesas Electronics brand. The part is functionally similar to other single-ended multiplexers in the family but is distinguished by its specific thermal rating and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements may include the HI9P0508 without the '-5' suffix for commercial temperature applications, or the HI9P0509 for differential configurations. Cross-reference with Intersil datasheets for equivalent pinouts and electrical characteristics.
