HA4404ACP

Analog Switches - Special Purpose Overview

The HA4404ACP is a specialized analog switch integrated circuit manufactured by Harris Corporation, designed specifically for video signal routing applications. It functions as a 4-channel by 1-channel video crosspoint switch, allowing the selection of one input signal from four available sources to be routed to a single output. The device is housed in a standard 16-DIP package with a width of 0.300 inches (7.62mm), suitable for through-hole mounting on printed circuit boards. It operates within a single supply voltage range of 4.5V to 5.5V or a dual supply configuration. The component supports an operating temperature range of 0°C to 70°C, ensuring reliable performance in commercial electronic environments.

Analog Switches - Special Purpose Feature Summary

• Provides dedicated routing capabilities for video signals using a 4x1 crosspoint architecture
• Supports operation with either a single positive supply or dual symmetric power supplies
• Utilizes a 16-pin dual in-line package compatible with standard through-hole assembly processes

Analog Switches - Special Purpose Applications

• Video signal switching and matrix routing systems
• Multi-source video input selection circuits
• Analog signal multiplexing in broadcast equipment

Analog Switches - Special Purpose Procurement Notes

Verify the specific manufacturer source when procuring this component, as Harris Corporation's legacy assets have been acquired by other entities such as Renesas Electronics. Confirm that the received unit matches the exact part number HA4404ACP and retains the original Harris branding if required for compatibility. Check the package condition and pin integrity upon receipt. Ensure the supplier provides valid traceability documentation. Be aware that availability may vary due to the component's status as a legacy industrial part.

Analog Switches - Special Purpose Selection Notes

Select the HA4404ACP when a dedicated hardware solution for routing four video inputs to a single output is required. This component is appropriate for designs needing a simple, low-complexity analog switch without digital control overhead. Consider the 16-DIP package size for board layout constraints. Evaluate the voltage requirements to ensure the system can provide the specified 4.5V to 5.5V single supply or equivalent dual rails. Verify that the operating temperature range meets the environmental conditions of the final application.

Analog Switches - Special Purpose Part Context

The HA4404ACP belongs to the family of special purpose analog switches produced by Harris Corporation. These components were widely used in professional audio and video processing equipment before the widespread adoption of fully digital video standards. The device represents a specific implementation of crosspoint switching technology, distinct from general-purpose logic switches or multiplexers. Its design focuses on maintaining signal integrity for analog video frequencies while providing isolation between unselected channels.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the proprietary nature of Harris Corporation's legacy analog switch designs and potential obsolescence, direct pin-to-pin replacements may require verification against current manufacturer datasheets or consultation with authorized distributors holding legacy inventory.
