3 Description
This 6-bit noninverting translator uses two separate
configurable power-supply rails. The A port is
designed to track VCCA. VCCA accepts any supply
voltage from 1.2V to 3.6V. The B port is designed
to track VCCB. VCCB accepts any supply voltage from
1.65V to 5.5V. This allows for universal low-voltage
bidirectional translation between any of the 1.2V, 1.5V,
1.8V, 2.5V, 3.3V, and 5V voltage nodes. VCCA should
not exceed VCCB.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance state.
The TXB0106-Q1 device 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.
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.
