STG3157 Low Voltage Low On Resistance SPDT Switch with Break-Before-Make Feat.

The STG3157 is a high-speed CMOS analog SPDT (single-pole double-throw) switch or 2:1 multiplexer/demultiplexer bus switch manufactured using silicon gate C2MOS technology. It is designed to operate from a 1.65 V to 5.5 V supply, making the device ideal for portable applications.

The STG3157 features very low on-resistance (< 9 Ω ) at VCC = 3.0 V. The IN input is provided to control the SPDT switch, and is compatible with standard CMOS output. Switch S1 is ON (connected to common port D) when the IN input is held high, and OFF (a high impedance state exists between the two ports) when IN is held low.

Switch S2 is ON (connected to common port D) when the IN input is held low and OFF (a high impedance state exists between the two ports) when IN is held high.

Additional key features are fast switching speed, break-before-make delay time, and very low power consumption. All inputs and outputs are equipped with protection circuits to protect against static discharge, giving them immunity from ESD and transient excess voltage

技术特性
