3 Description
This TXB0104 4-bit noninverting translator uses two
separate configurable power-supply rails. The A port
is designed to track VCCA. VCCA accepts any supply
voltage from 1.2 V to 3.6 V. The B port is designed to
track VCCB. VCCB accepts any supply voltage from
1.65 V to 5.5 V. 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 input is low, all outputs are placed in
the high-impedance state. To ensure the highimpedance
state during power up or power down, OE
must be tied to GND through a pulldown resistor The
current sourcing capability of the driver determines
the minimum value of the resistor.
The TXB0104 device is designed so the OE input
circuit is supplied by VCCA.
This device is fully specified for partial power-down
applications using I OFF. The I OFF circuitry disables
the outputs, which prevents damaging current
backflow throug
