description
The SN74CBTD3306 features two independent line switches. Each switch is disabled when the associated
output-enable (OE) input is high. A diode to V_CC is integrated on the chip to allow for level shifting between 5-V
inputs and 3.3-V outputs.
The SN74CBTD3306 is characterized for operation from –40°C to 85°C.
