ISL43143IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43143IR is a high-speed, low-power analog crosspoint switch manufactured by Intersil. It features a 4x4 matrix topology with four inputs and four outputs, housed in a 28-lead TSSOP package. The device operates on a single supply voltage ranging from 2.7V to 5.5V, with a typical operating voltage of 5V. It supports a bandwidth of 600MHz and offers an off-isolation of 70dB at 10MHz. Key electrical parameters include a maximum on-resistance of 12 ohms and a channel-to-channel matching of 0.1 ohm. The component functions within a temperature range of -40°C to +85°C and consumes 105mW when enabled.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IR' corresponds to the tape-and-reel packaging variant rather than tube packaging. Confirm RoHS compliance status as active. Ensure the supplier provides traceability documentation consistent with Intersil or Renesas manufacturing standards. Validate that the component matches the 28-lead TSSOP physical dimensions before integration into the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a 4x4 analog switching matrix is required for signals up to 600MHz. Compare against the HA4314B if only 4x1 routing is needed, as the ISL43143IR offers expanded connectivity. Consider the 28-lead TSSOP package constraints during PCB layout. Verify that the 2.7V to 5.5V supply range aligns with the system power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Intersil (now Renesas) family of high-performance analog crosspoint switches. It complements other models like the HA4314B and HA4404B by providing a larger 4x4 matrix configuration. The series is designed for applications requiring high isolation and minimal signal distortion in professional audio and video environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The HA4314B serves as a functional substitute for 4x1 configurations but lacks the full 4x4 matrix. Verify pin compatibility and control logic differences when replacing with other Intersil crosspoint switches. Check datasheets for variations in bandwidth and supply voltage requirements.
