TXB0108

8-BIT BIDIRECTIONAL VOLTAGE-LEVEL TRANSLATOR

WITH AUTO-DIRECTION SENSING AND

±15-kV ESD PROTECTION

SCES643A – NOVEMBER 2006 – REVISED JANUARY 2007

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.
