ISL54214IRTZ

Analog Switches - Special Purpose Overview

The ISL54214IRTZ is a single-supply dual SP3T analog switch designed for multiplexing audio stereo signals and two USB 2.0 High-Speed differential data signals. It operates from a single supply voltage ranging from 2.7V to 4.6V. The device features a -3dB bandwidth of 700MHz, suitable for passing USB High-Speed signals at 480Mbps with minimal distortion. Audio channels support signal swings below ground, handling ±1V ground-referenced audio signals with less than 0.03% THD+N when driving 5mW into 32Ω loads. The USB switch cells exhibit low ON capacitance of 8pF. Maximum on-resistance is specified at 2.8 ohms for audio applications and 8 ohms for USB applications. The component is housed in a 12-TQFN (3x3) package and operates within a temperature range of -40°C to +85°C.
