3 Description
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
V_CCA. VCCA accepts any supply voltage from 1.2 V to
3.6 V. The B port is designed to track V_CCB. 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. V_CCA should not
exceed V_CCB.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance state. 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.
The TXB0104 is designed so that the OE input circuit
is supplied by V_CCA.
This device is fully specified for partial-power-down
applications using I_off. The I_off circuitry disables the
outputs, preventing damaging current backflow
through the device when it is powered down.
