ISL54216IRTZ-T

Analog Switches - Special Purpose Overview

The ISL54216IRTZ-T is a dual-channel USB and UART multiplexer IC manufactured by Renesas Electronics. It features two independent 3:1 multiplexer circuits housed in a compact 12-lead TQFN package measuring 3x3 mm. The device operates on a single supply voltage ranging from 2.7V to 4.6V, with a typical operating voltage of 3.3V. Key electrical parameters include a maximum on-resistance of 8 ohms, a -3dB bandwidth of 800MHz, and maximum switching times for both turn-on and turn-off at 125 ns. It supports USB 2.0 high-speed data rates and includes break-before-make switching characteristics. The component functions within an ambient temperature range of -40°C to +85°C.
