DESCRIPTION/ORDERING INFORMATION  
This two-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to  
track VCCA. VCCA accepts any supply voltage from 1.65 V to 3.6 V. The B port is designed to track VCCB. VCCA  
must be less than or equal to VCCB. VCCB accepts any supply voltage from 2.3 V to 5.5 V. This allows for  
low-voltage bidirectional translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.  
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.

www.ti.com/sc/package.  
(2) DCT: The actual top-side marking has three additional characters that designate the year, month, and assembly/test site.  
DCU: The actual top-side marking has one additional character that designates the assembly/test site.  
YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following  
character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb, • = Pb-free).

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings  
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating  
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.  
(2) The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.  
(3) The value of VCCA and VCCB are provided in the recommended operating conditions table.  
(4) The package thermal impedance is calculated in accordance with JESD 51-7.

PRINCIPLES OF OPERATION  
Applications  
The TXS0102 can be used in level-translation applications for interfacing devices or systems operating at  
different interface voltages with one another. The TXS0102 is ideal for use in applications where an open-drain  
driver is connected to the data I/Os. The TXS0102 can also be used in applications where a push-pull driver is  
connected to the data I/Os, but the TXB0102 might be a better option for such push-pull applications.  
Architecture  
The TXS0102 architecture (see Figure 1) does not require a direction-control signal to control the direction of  
data flow from A to B or from B to A.

Figure 1. Architecture of a TXS01xx Cell  
Each A-port I/O has an internal 10-kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10-kΩ pullup  
resistor to VCCB. The output one-shots detect rising edges on the A or B ports. During a rising edge, the  
one-shot turns on the PMOS transistors (T1,T2) for a short duration, which speeds up the low-to-high transition.  
Input Driver Requirements  
The fall time (tfA, tfB) of a signal depends on the output impedance of the external device driving the data I/Os of  
the TXS0102. Similarly, the tPHL and max data rates also depend on the output impedance of the external driver.  
The values for tfA, tfB, tPHL, and maximum data rates in the data sheet assume that the output impedance of the  
external driver is less than 50 Ω.  
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.  
Enable and Disable  
The TXS0102 has an OE input that is used to disable the device by setting OE low, which places all I/Os in the  
Hi-Z state. The disable time (tdis) indicates the delay between the time when OE goes low and when the outputs  
actually get 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  
Each A-port I/O has an internal 10-kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10-kΩ pullup  
resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O  
to VCCA or VCCB (in parallel with the internal 10-kΩ resistors).
