HFA9P0001-5

Overview

The HFA9P0001-5 is a high-speed analog switch manufactured by Harris Corporation. It functions as a single-pole double-throw (SPDT) multiplexer designed for applications requiring fast switching and low distortion. The device operates with dual power supplies, typically ±15V, and features a compact surface-mount package. Key electrical characteristics include a nominal on-resistance of 400 Ω and an off-isolation of 68 dB at DC. It supports signal frequencies up to several hundred megahertz, making it suitable for video and RF signal routing.

Feature Summary

• Provides single-pole double-throw switching capability for signal routing
• Features low on-resistance for minimal signal attenuation
• Offers high off-isolation to prevent signal leakage between channels
• Designed for wide bandwidth operation in analog signal paths

Applications

• Video signal routing and switching systems
• RF signal distribution networks
• Test and measurement equipment signal paths
• Data acquisition system channel selection

Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Ensure the specific suffix matches the required pinout and packaging variant. Confirm RoHS compliance status if environmental regulations apply to the end product. Cross-reference the datasheet revision to ensure compatibility with current design specifications.

Selection Notes

Select this component when a reliable SPDT switch is needed for analog signals. Consider the on-resistance value relative to the load impedance to minimize voltage drop. Evaluate the supply voltage requirements against the available system rails. Check the operating temperature range to ensure suitability for the intended environment.

Part Context

This part belongs to the HFA9 series of high-performance analog switches from Harris Corporation. The series is known for its use in professional audio and video applications due to its low distortion characteristics. The HFA9P0001-5 specifically denotes a packaged version of this technology, integrating the switching matrix into a standard industrial outline.

Replacement Considerations

Potential substitutes may include other SPDT analog switches from manufacturers like Analog Devices or Texas Instruments. Verify that replacement parts match the pin configuration and supply voltage requirements. Ensure the alternative device meets or exceeds the original on-resistance and isolation specifications.
