SGM3799数据手册SGMICRO中文资料规格书

描述 Description

The SGM3799 is a dual, DPDT (double-pole/double-throw), TTL/CMOS compatible analog switch. It operates from a 1.8V to 4.35V single power supply.
The SGM3799 features low on-resistance, low voltage and fast switching times. The high performances make it very suitable for multiple applications, such as portable equipment, audio and video signal routing, etc. In addition, the SGM3799 can be used as a dual 2-to-1 multiplexer/demultiplexer because it has two logic control inputs. Low power consumption is also one of the important reasons that make it a good choice.
The SGM3799 is available in a Green TQFN-2.6×1.8-16L package. It operates over an ambient temperature range of -40℃ to +85℃.
