9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The TXS0104E device can be used in level-translation applications for interfacing devices or systems operating
at different interface voltages with one another. The TXS0104E device is ideal for use in applications where an
open-drain driver is connected to the data I/Os. The TXS0104E device can also be used in applications where a
push-pull driver is connected to the data I/Os, but the TXB0104 device might be a better option for such push-
pull applications.
9.2 Typical Application
Figure 11. Application Schematic
9.2.1 Design Requirements
For this design example, use the parameters listed in Table 1.
Table 1. Design Parameters
DESIGN PARAMETER EXAMPLE VALUE
Input voltage range 1.65 to 3.6 V
Output voltage range 2.3 to 5.5 V
9.2.2 Detailed Design Procedure
To begin the design process, determine the following:
• Input voltage range
– Use the supply voltage of the device that is driving the TXS0104E device to determine the input voltage
range. For a valid logic high the value must exceed the V
IH
of the input port. For a valid logic low the value
must be less than the V
IL
of the input port.
• Output voltage range
– Use the supply voltage of the device that the TXS0104E device is driving to determine the output voltage
range.
