HI9P5051-9S2485

Overview

The HI9P5051-9S2485 is a CMOS analog switch IC manufactured by Intersil, now part of Renesas Electronics. It features two independent double-pole single-throw (DPST) channels housed in a 16-lead SOIC-Narrow package. The device operates on dual supplies ranging from 5 V to 15 V. Key electrical specifications include a maximum on-resistance of 45 Ohms and a maximum power dissipation of 1.5 mW. It supports a switching current of 30 mA with a maximum operating temperature of +85°C.

Feature Summary

• Dual-channel SPDT configuration for signal routing
• CMOS technology for low power consumption
• Industrial temperature range operation

Applications

• Signal multiplexing systems
• Data acquisition circuits
• Audio signal switching

Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers due to potential obsolescence status. Confirm lot traceability and moisture sensitivity level handling requirements upon receipt. Ensure the specific suffix matches the required package variant. Request fresh date codes if long-term storage stability is critical for the application timeline.

Selection Notes

Select this component when dual isolated signal paths are required within a compact surface-mount footprint. Evaluate the 45 Ohm on-resistance against signal integrity requirements for the specific voltage levels. Consider the dual supply requirement during system power design. Verify that the 30 mA switching current capability meets the load demands of the connected circuitry without exceeding thermal limits.

Part Context

This part belongs to the HI-5051 series of CMOS analog switches. The series is characterized by high-speed switching and low charge injection. The HI9P5051 variant specifically denotes the industrial temperature grade and standard plastic packaging. It serves as a general-purpose switching solution for mixed-signal applications requiring reliable isolation between channels.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that any substitute maintains the 16-lead SOIC package and dual supply voltage range. Ensure equivalent on-resistance and switching speed parameters are met for functional compatibility.
