低压0.6ヘ典型值与断裂前先功能和15 kV ESD保护单SPDT开关 Low voltage 0.6 ヘ typ single SPDT switch with break-before-make feature and 15 kV ESD protection
The STG4158 is a high-speed CMOS low-voltage single analog SPDT single-pole dual throw switch or 2:1 multiplexer/demultiplexer switch fabricated in silicon gate C2MOS technology. Designed to operate from 1.65 to 4.5 V, this device is ideal for portable applications.
It offers low ON-resistance 0.6 Ω at VCC= 4.5 V typical TA= 25 °C. The SEL input threshold is compatible with 1.8 V, and provides control to the switches.
The switch S1 is ON connected to common port D when the SEL input is held high and OFF high-impedance state exists between the two ports when SEL is held low. The switch S2 is ON connected to common port D when the SEL input is held low and OFF high-impedance state exists between the two ports when SEL is held high.
The SEL input has an integrated weak pull-down resistor to prevent the SEL signal from floating. For low-power consumption, the SEL input must be grounded.
The STG4158 features power-off and overvoltage protection, enabling the device to be isolated during voltage fault events.
