SGM7226数据手册SGMICRO中文资料规格书

描述 Description

The SGM7226 is a DPDT (double-pole/double-throw) analog switch. It operates from a 1.8V to 5.5V single power supply and can be powered directly by VBUS. Each switch of the SGM7226 is bidirectional, which can ensure that the high speed signals have little or no attenuation at the outputs.
The SGM7226 features high speed, low power and wide bandwidth. The high performances make it very suitable for multiple applications, such as cellular phones and computer peripherals, etc.
The SGM7226 has a power-off protection. It can prevent accidental signal leakage and ensure system reliability under power-down and over-voltage conditions. In addition, the device is capable of withstanding a VBUS short to D+ or D- when the device is either powered on or powered off due to the special circuitry on the D+/D- pins.
The SGM7226 is available in a Green TQFN-2.6×1.8-16L package. It operates over an ambient temperature range of -40℃ to +85℃.
