HA4314BCA

Analog Switches - Special Purpose Overview

The HA4314BCA is a 4x1 video crosspoint switch manufactured by Harris Corporation, designed for professional video switching and high-performance routing applications. It operates with a nominal supply voltage of 5 V, ranging from 4.5 V to 5.5 V, and supports a negative supply voltage between -4.5 V and -5.5 V. The device features four channels within one function, housed in a 16-lead PDSO plastic package. Key electrical specifications include a bandwidth of 400 MHz, a typical off-isolation of 70 dB, and low power dissipation of 105 mW when enabled and 4 mW when disabled. It functions without an external current source and exhibits fast switching with symmetric slew rates.

Analog Switches - Special Purpose Feature Summary

• Provides wide bandwidth signal routing suitable for HDTV and computer monitor applications
• Maintains excellent differential gain and phase performance across the signal path
• Switches output to a high impedance state when disabled for matrix routing compatibility

Analog Switches - Special Purpose Applications

• Professional video switching systems
• HDTV signal routing
• Computer monitor signal distribution

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and pin count. The BCA designation indicates a 16-lead small outline package, distinct from other variants like the BCP which uses a 14-lead SOIC. Confirm RoHS compliance status and active lifecycle stage through official Harris or authorized distributor channels before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring a single-ended 4x1 crosspoint configuration with high isolation. Ensure the design accommodates the specified dual supply voltage range. Consider alternative models such as the HA4404B if tally outputs are required, or the HA4344B if synchronous control signals are necessary for the system architecture.

Analog Switches - Special Purpose Part Context

This component belongs to the HA4314B series of wide bandwidth crosspoint switches. It is part of Harris Corporation's analog mixed-signal IC portfolio focused on signal routing solutions. The device is engineered to replace older relay-based switching mechanisms in video infrastructure, offering solid-state reliability and faster transition times.

Analog Switches - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts due to potential differences in pin configurations between the 16-lead BCA and other package variants in the series.
