Power Up
During operation, ensure that VCCA ≤ VCCB at all times. During power-up sequencing, VCCA ≥ VCCB does not
damage the device, so any power supply can be ramped up first. The TXB0102 has circuitry that disables all
output ports when either VCC is switched off (VCCA/B = 0 V).
Enable and Disable
The TXB0102 has an OE input that is used to disable the device by setting OE = low, which places all I/Os in the
high-impedance (Hi-Z) state. The disable time (tdis) indicates the delay between when OE goes low and when the
outputs are disabled (Hi-Z). The enable time (ten) indicates the amount of time the user must allow for the one-
shot circuitry to become operational after OE is taken high.
Pullup or Pulldown Resistors on I/O Lines
The TXB0102 is designed to drive capacitive loads of up to 70 pF. The output drivers of the TXB0102 have low
dc drive strength. If pullup or pulldown resistors are connected externally to the data I/Os, their values must be
kept higher than 50 k
to ensure that they do not contend with the output drivers of the TXB0102.
For the same reason, the TXB0102 should not be used in applications such as I2C or 1-Wire where an open-
drain driver is connected on the bidirectional data I/O. For these applications, use a device from the TI TXS01xx
series of level translators.
