ISL54209IRTZ

Analog Switches - Special Purpose Overview

The ISL54209IRTZ is a high-speed USB 2.0 and audio multiplexer switch IC manufactured by Intersil, now part of Renesas Electronics. It features a dual SPDT configuration housed in a compact 10-lead TDFN (3x3 mm) package with an exposed pad. The device supports a single supply voltage range from 2.7 V to 5.5 V, with typical operation at 3 V or 5 V. Key electrical specifications include a maximum on-resistance of 8 Ohms, a bandwidth of 742 MHz, and fast switching times with a maximum turn-on time of 35 ns and turn-off time of 27 ns. It operates within a temperature range of -40°C to +85°C and draws a maximum supply current of 30 nA.
