HI9P0222-9

Overview

The HI9P0222-9 is a high-frequency analog switch manufactured by Harris Corporation. It belongs to the HI-222 family, which complements the company's high-speed operational amplifiers and buffers. The device is fabricated using Dielectric Isolation process technology combined with silicon gate techniques to enhance key performance parameters. This construction optimizes crosstalk and off-isolation characteristics through a T-switch configuration and utilizes non-connected pins for extended shielding capabilities.

Feature Summary

• High-frequency operation suitable for demanding signal switching applications
• Dielectric isolation process ensures enhanced electrical stability and performance
• T-switch configuration optimizes crosstalk and off-isolation metrics
• Non-connected pins provide extended shielding for improved signal integrity

Applications

• High frequency analog signal routing
• Video signal switching systems
• Audio/Video switch circuits
• Designs requiring improved switching performance

Procurement Notes

Verify the manufacturer origin as Harris Corporation, noting its historical status prior to the L3Harris merger. Confirm the package type matches the specific variant requirements. Ensure compatibility with TTL compatible logic levels if digital control is involved. Check for lead-free compliance status against current regulatory standards. Validate pinout configurations against schematic diagrams before integration.

Selection Notes

Select this component when wideband operation and low differential gain are required. Consider the fast switching speeds for time-sensitive applications. Evaluate the low on-resistance for minimal signal attenuation. Assess the need for dielectric isolation benefits over standard processes. Verify that the dual SPST architecture fits the circuit topology constraints.

Part Context

Harris Corporation specialized in surveillance solutions, microwave weaponry, and electronic warfare before merging with L3 Technologies in 2019 to form L3Harris Technologies. The HI-222 series represents their legacy in high-speed analog integrated circuits. These components were designed to complement the broader family of high-speed op amps and buffers offered by the company during its independent operational period.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official L3Harris catalogs or authorized distributors for current equivalent listings. Cross-reference pinouts and electrical specifications carefully when evaluating potential alternatives from other manufacturers.
