com on IN1 to OUT, or IN2 to OUT, through a very low RDS(ON) power MOSFET that minimizes voltage drops and power dissipation.
The enable (EN) and select (SEL) pin voltages control the operational state of the internal power MOSFET switches.
Once enabled, the SEL pin will switch between the IN1 and IN2 i...
