PRODUCTION DATA
For the bidirectional translation configuration (higher voltage to lower voltage or lower voltage to higher voltage), the EN input must be connected to Vref_B and both pins must be pulled up to the HIGH side VCCB through a bias resistor (typically 200kΩ). This allows Vref_B to regulate the EN input and bias the channels for proper translation. A filter capacitor on Vref_B is recommended for a stable supply at the device. The controller output driver can be push-pull or open-drain (pull-up resistors may be required) and the peripheral device output can be push-pull or open-drain (pull-up resistors are required to pull the Bn outputs to VPU).
