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 1.2 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.
The TXB0106 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.
