ISL43142IB-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43142IB-T is a high-speed, low-power analog switch manufactured by Renesas Electronics Corporation. It features a single-pole double-throw (SPDT) configuration with one common input and two selectable outputs. The device operates on a single supply voltage ranging from 2.7V to 5.5V, ensuring compatibility with various digital logic families. Key electrical parameters include a typical on-resistance of 8 ohms and an on-resistance matching of 0.05 ohms across the full temperature range. The switch supports data rates up to 250 Mbps and offers low charge injection of 0.1 pC. It is housed in an 8-lead TSSOP package, designed for applications requiring signal routing in portable and battery-powered equipment.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IB-T' against the manufacturer's official datasheet to confirm the tape-and-reel packaging quantity and temperature grade. Ensure the component matches the required RoHS compliance status for your region. Cross-reference the date code with current production status to avoid obsolete stock issues during procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact SPDT switch is needed for signals below 100MHz or moderate data rates. Compare on-resistance stability and leakage current requirements against alternative switches in the same package. Consider the operating voltage range to ensure compatibility with the system's power rails without level shifting.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to Renesas's family of high-speed analog switches, previously associated with Intersil technology. It serves as a solution for signal multiplexing in space-constrained designs.
