This 4-bit non-inverting translator uses two separate
configurable power-supply rails. The A port is
designed to track V
CCA
. V
accepts any supply
CCA
voltage from 1.2 V to 3.6 V. The B port is designed to
track V
CCB
. V
accepts any supply voltage from
CCB
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
should not exceed V
CCA
CCB
.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance state. 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.
The TXB0104 is designed so that the OE input circuit
is supplied by V
CCA
.
This device is fully specified for partial-power-down
applications using I
. The I
off
circuitry disables the
off
outputs, preventing damaging current backflow
through the device when it is powered down.

TXB0104
SCES650G –APRIL 2006–REVISED NOVEMBER 2014
A. N.C. − No internal connection
B. For RGY, if the exposed center pad is used, it must only be connected as a secondary ground or left
electrically open.
C. Pullup resistors are not required on both sides for Logic I/O.
D. If pull up or pull down resistors are needed, the resistor value must be over 50 kΩ.
E. 50 kΩ is a safe recommended value, if the customer can accept higher VOLor lower VOH, smaller pullup or
pulldown resistor is allowed, the draft estimation is VOL= V
RDW/(4.5 k + RDW).
F. If pullup resistors are needed, please refer to the TXS0104 or contact TI.
G. For detailed information, please refer to application note SCEA043.
