HI4P0222-5

Analog Switches - Special Purpose Overview

The HI4P0222-5 is a dual single-pole single-throw (SPST) high-frequency analog switch designed for video applications. It features two independent channels within a 20-pin Plastic Leadless Chip Carrier (PLCC) package measuring 9x9 mm. The device operates with a nominal negative supply voltage of -15 V and exhibits a maximum on-state resistance of 50 Ω. Key electrical specifications include an off-state isolation of 65 dB, supporting TTL-compatible control logic for efficient system integration.

Analog Switches - Special Purpose Feature Summary

• Utilizes dielectric isolation process and silicon gate technology to enhance key performance parameters
• Employs T-switch configuration and non-connected pins for extended shielding to optimize crosstalk and off-isolation
• Provides wideband operation capabilities suitable for high-frequency signal routing
• Features low differential gain and phase distortion for accurate signal transmission

Analog Switches - Special Purpose Applications

• Video signal switching systems
• High-frequency analog signal routing
• TTL-compatible interface designs requiring improved switching performance

Analog Switches - Special Purpose Procurement Notes

Verify the specific package variant, as the HI-222 series includes multiple pinout configurations such as DIP and PLCC. Confirm that the 20-pin PLCC version matches the required footprint. Check for lead-free compliance requirements against the standard RoHS status. Ensure the operating temperature range of 0 to 75 °C aligns with the environmental conditions of the target application.

Analog Switches - Special Purpose Selection Notes

Select this component when dual SPST switching with high off-isolation is required. The 50 Ω on-resistance suits general-purpose video paths rather than precision audio. Consider the 20-pin PLCC package for surface-mount assembly needs. Verify TTL compatibility if interfacing directly with digital logic controllers without additional level shifting circuitry.

Analog Switches - Special Purpose Part Context

The HI-222 series comprises high-speed analog switches complementing Harris op-amp families. The HI4P0222-5 specifically denotes the dual-channel variant in a 20-lead PLCC package. This part belongs to a family optimized for video and RF applications where low distortion and fast switching are critical. Other variants exist in different packages like CERDIP or PDIP.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include other HI-222 series variants with compatible pinouts. Verify functional equivalence regarding the 50 Ω on-resistance and 65 dB isolation. Ensure the replacement supports the same -15 V supply requirement and TTL input levels.
