HA4314BCB

Analog Switches - Special Purpose Overview

The HA4314BCB is a 4-channel, 1-input video crosspoint switch manufactured by Renesas Electronics Corporation (formerly Intersil). Designed for professional video switching and HDTV applications, it operates within a supply voltage range of 4.5 V to 5.5 V, with a rated voltage of 5 V. The device features a bandwidth of 400 MHz and supports surface-mount PDSO14 packaging with 14 terminals in a small outline rectangular form. It exhibits low power dissipation of 105 mW when enabled and 4 mW when disabled. The component functions across an operating temperature range of 0°C to 70°C.

Analog Switches - Special Purpose Feature Summary

• Provides high-performance routing matrix capabilities through excellent off-isolation and symmetric slew rates.
• Eliminates the need for external current sources due to integrated circuit design.
• Switches outputs to a high-impedance state when disabled to prevent signal interference.

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 'BCB' against official Renesas documentation to confirm package variant and compliance status. Ensure the source document explicitly identifies the manufacturer as Renesas or Intersil. Confirm RoHS compliance and active status directly from the datasheet before procurement planning.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring wide bandwidth video signal routing without external biasing requirements. Consider the 400 MHz bandwidth limit for signal integrity. Verify that the single-input architecture meets the system's switching topology needs compared to multi-output alternatives.

Analog Switches - Special Purpose Part Context

This component belongs to the family of analog crosspoint switches originally developed by Intersil, now part of Renesas Electronics. It serves as a specialized solution for high-frequency video signal management, distinct from general-purpose logic switches or digital multiplexers.

Analog Switches - Special Purpose Replacement Considerations

Consult the HA4404B for versions with tally outputs or the HA4344B for synchronous control signals. Review data sheets for compatible crosspoint switches if pin-out or functional differences are critical to the existing design.

Analog Switches - Special Purpose FAQ

Does the HA4314BCB require an external current source?

No, the circuit features an internal design that requires no external current source.
