The STG3157 is a low voltage low on-resistance SPDT switch with high speed and low power dissipation. It operates from 1.65V to 5.5V, making it ideal for portable applications.
The STG3157 is a high-speed CMOS analog SPDT (single-pole double-throw) switch or 2:1 multiplexer/demultiplexer bus switch manufactured using silicon gate CMOS technology. It is designed to operate from a 1.65 V to 5.5 V supply, making the device ideal for portable applications. The device features very low on-resistance (<9 Ω) at VDD = 3.0 V and includes a TTL threshold ON control input compatible with standard CMOS outputs.
