8.4 Power Supply Recommendations

The TXV0108-Q1 uses two separate configurable power supply rails, VCCA and VCCB. The A port and B port are designed to track VCCA and VCCB, respectively, allowing for low-voltage fixed translation between any of the 1.8-V, 2.5-V and 3.3-V voltage nodes.

The output-enable OE input circuit is designed to be supplied by VCCA. When the OE input is high, all outputs are placed in the high-impedance state. To put the outputs in a high-impedance state during power up or power down, tie the OE input pin to VCCA through a pullup resistor and do not be enable it until VCCA and VCCB are fully ramped and stable. The current-sinking capability of the driver determines the minimum value of the pullup resistor to VCCA.
