No power supply sequencing required - either VCCA or VCCB can be ramped up first
VCCA can be >,=,< VCCB
Voltage-level translators address the challenges posed by simultaneous use of different supply-voltage levels on the same circuit board. This 4-bit non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.1V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes.
When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. To establish high-impedance state during power up or power down, OE must be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
The TXB0104W is designed so that the OE input circuit is supplied by VCCA.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
