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 1.65 V to 3.6 V. VCCA must be less than or equal to
VCCB. The B port is designed to track VCCB.
VCCB accepts any supply voltage from 2.3 V to 5.5 V. This allows for
low-voltage bidirectional translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage
When the output-enable (OE) input is low, all outputs are placed in the high-impedance
The TXS0104E is designed so that the OE input circuit is supplied by
To ensure the high-impedance state during power up or power down, OE should be tied to
GND through a pulldown resistor; the minimum value of the resistor is determined by the
current-sourcing capability of the driver.
