ISL54401IRUZ-T

Analog Switches - Special Purpose Overview

The ISL54401IRUZ-T is a high-bandwidth, low-capacitance audio and data switch manufactured by Intersil. It features a dual SPST configuration housed in an 8-pin UTQFN package. The device operates within a supply voltage range of 2.7 V to 5.5 V, with a maximum on-resistance of 3.5 Ohms. Key electrical parameters include a maximum operating frequency of 100 MHz, a typical turn-on time of 5 microseconds, and an idle time of 45 nanoseconds. It supports a DC switch current of 150 mA and draws a quiescent current of 7 µA. The component functions reliably across an industrial temperature range from -40°C to +85°C.
