Product Summary
The SN74CBTD3306PWR is a dual fet bus switch with level shifting. The SN74CBTD3306PWR features two independent line switches. Each switch is disabled when the associated output-enable (OE) input is high. A diode to VCC is integrated on the chip to allow for level shifting between 5-V inputs and 3.3-V outputs.
