7.3 Power Supply Recommendations

During operation, ensure that VCCA ≤ VCCB at all times. During power-up sequencing, VCCA ≥ VCCB does not damage the device, so any power supply can be ramped up first. The TXB0106-Q1 device has circuitry that disables all output ports when either VCC is switched off (VCCA or VCCB= 0V). The output-enable (OE) input circuit is designed so that it is supplied by VCCA, and when the (OE) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state of the outputs during power up or power down, the OE input 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.
