ISL54212IRTZ-T

Analog Switches - Special Purpose Overview

The ISL54212IRTZ-T is a dual-channel USB switch IC manufactured by Renesas Electronics Corporation, designed for audio and USB applications. It features a 2:1 multiplexer configuration with SPDT switching circuits housed in a 10-VFDFN package with an exposed pad. The device operates on a single supply voltage ranging from 2.5V to 5.5V and supports a -3dB bandwidth of 630MHz. Maximum on-resistance is specified at 4 ohms for audio signals and 5 ohms for USB data lines. It functions within a temperature range of -40°C to 85°C and includes break-before-make timing characteristics compliant with USB 2.0 standards.
