SGM7223数据手册SGMICRO中文资料规格书

描述 Description

The SGM7223 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 SGM7223 is bidirectional, which can ensure that the high speed signals have little or no attenuation at the outputs.
The SGM7223 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 SGM7223 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 SGM7223 is available in a Green TQFN-2.1×1.6-10L package. It operates over an ambient temperature range of -40℃ to +85℃.
