10 Power Supply Recommendations

The TXS0206A does not require power sequencing between VCCA and VCCB during power-up so the power-supply rails can be ramped in any order.

The EN pin is referenced to VCCA and when configured to low, will place all outputs into a high-impedance state. To ensure the high-impedance state of the outputs during power up or power down, the EN pin must be tied to GND through a pulldown resistor and must not be enabled until VCCA and VCCB are fully ramped and stable. The minimum value of the pulldown resistor to ground is determined by the current-sourcing capability of the driver controlling the EN pin.

Finally, the EN pin may be shorted to VCCA if the application does not require use of the high-impedance state at any time.
