9.3 Power Supply Recommendations

The TXS0104E device uses two separate configurable power-supply rails, VCCA and VCCB. VCCB accepts any supply voltage from 2.3 V to 5.5 V and VCCA accepts any supply voltage from 1.65 V to 3.6 V as long as Vs is less than or equal to VCCB. The A port and B port are designed to track VCCA and VCCB respectively allowing for low-voltage bidirectional translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.

The TXS0104E device does not require power sequencing between VCCA and VCCB during power-up so the power-supply rails can be ramped in any order. A VCCA value greater than or equal to VCCB (VCCA ≥ VCCB) does not damage the device, but during operation, VCCA must be less than or equal to VCCB (VCCA ≤ VCCB) at all times.

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. For 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.
