ISL54409IRTZ-T

Analog Switches - Special Purpose Overview

The ISL54409IRTZ-T is a dual single-pole single-throw (SPST) USB switch integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 2.7 V to 5 V and draws a typical quiescent current of 7 µA. The device features a maximum on-resistance of 2.8 Ohms and supports a DC switch current of 150 mA. Switching performance includes a maximum turn-on time of 5 µs and a maximum turn-off time of 45 ns. It is housed in an 8-pin TDFN package and functions reliably across an operating temperature range from -40°C to +85°C.
