GENERAL DEscriptION

The SGM7222 is a DPDT (double-pole/double-throw) analog switch. It operates from a 1.8V to 4.3V single power supply. Each switch of the SGM7222 is bidirectional, which can ensure that the high speed signals have little or no attenuation at the outputs.

The SGM7222 features high speed, low bit-to-bit skew and wide bandwidth. The high performances make it very suitable for multiple applications, such as cellular phones and computer peripherals, etc.

The SGM7222 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 because of the special circuitry on the D+/D- pins.

The SGM7222 is available in Green T×1.4-10L, MSOP-10 and UT×1.4-10L packages. It operates over an ambient temperature range of -40℃ to +85℃.
