The TXB0102
device is a 2-bit noninverting translator that uses two
separate configurable power-supply rails. The A port is
designed to track V CCA. V CCA accepts
any supply voltage from 1.2 V to 3.6 V. The B port is
designed to track V CCB. V CCB 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 must not exceed
V CCB.When the
output-enable (OE) input is low, all outputs are placed in
the high-impedance state.This device
is fully specified for partial-power-down applications using
I off. The I off circuitry
disables the outputs when the device is powered down. This
inhibits current backflow into the device which prevents
damage to the device.OE must be
tied to GND through a pulldown resistor to assure the
high-impedance state during power up or power down; the
minimum value of the resistor is determined by the
current-sourcing capability of the driver.NanoFree™
technology is a major breakthrough in IC packaging concepts,
using the die as the package.
