DescriptionThis TXB0104 4-bit noninverting translator uses two
separate configurable power-supply rails. TheA port designedto track VCCA. VCCA accepts any supply
voltage from 1.2Vto 3.6V. TheB portis designedto
track VCCB. VCCB accepts any supply voltage from
1.65Vto 5.5V. This allows for universal low-voltage
bidirectional translation between any of the 1.2-V,
1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.
VCCA must not exceed VCCB.
When the OE inputis low,all outputs are placedin
the high-impedance state. To ensure the high-
impedance state during powerupor power down, OE
must be tiedto GND througha pulldown resistor The
current sourcing capabilityof the driver determines
the minimum valueof the resistor.
The TXB0104 deviceis designed so the OE input
circuitis suppliedby VCCA.
This deviceis fully specified for partial power-down
applications usingI OFF. TheI OFF circuitry disables
the outputs, which prevents damaging current
backflow through the device when the deviceis
powered down.
