HI9P0508-9

Analog Switches, Multiplexers, Demultiplexers Overview

The HI9P0508-9 is a high-speed analog multiplexer switch IC manufactured by Renesas Electronics Corporation. It features an 8-channel to single-ended configuration, allowing one of eight input signals to be routed to a common output. The device operates with dual power supplies ranging from ±15V to ±22V and supports single supply operation up to 30V. Key electrical specifications include a maximum on-resistance of 400 Ohms, a maximum on-time of 250 ns, and a maximum off-time of 250 ns. It is housed in a 16-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential obsolescence risks associated with legacy Intersil/Renesas product lines. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for recent Product Change Notifications (PCNs) regarding manufacturing site changes or material substitutions that may affect long-term availability and performance consistency.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog multiplexer with moderate speed requirements is needed. Ensure the application voltage does not exceed the absolute maximum ratings of ±22V for dual supplies. Consider the 400 Ohm on-resistance impact on signal integrity for low-voltage inputs. Verify that the SOIC-16 footprint matches the PCB layout constraints and that thermal management meets the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HI-506 series of analog switches, originally developed by Harris Semiconductor and later acquired by Intersil, now part of Renesas Electronics. The HI9P0508-9 variant specifically denotes the industrial temperature grade (-40°C to +85°C) and the 9 suffix often indicates specific packaging or testing options within the family. It serves as a functional alternative to other 8-channel muxes in legacy industrial designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Renesas official cross-reference guides or contact technical support for qualified replacements, considering parameters such as channel count, on-resistance, and package compatibility.
