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 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 should not
exceed VCCB.
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 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.
