STMICROELECTRONICS  STG719STR  模拟开关, SPDT, 1 放大器, 4 ohm, 1.8V 至 5.5V, SOT-23, 6 引脚

The STG719 is a high-speed SPDT single pole double throw switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.8 V to 5.5 V, making this device ideal for portable applications, audio signal routing, video switching, mobile, and communication systems. It offers 4 Ω ON-resistance max at 5 V, 25 °C and very low ON-resistance flatness. Additional key features include a fast switching speed tON = 7 ns and tOFF = 4.5 ns, break before make delay time, and low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage. It is available in the commercial and extended temperature range.
