What is TXS0102DQER used for?
The TXS0102DQER is commonly used to bridge logic-level mismatches between microcontrollers, sensors, and peripherals operating at different supply voltages, such as connecting a 1.8 V sensor bus to a 3.3 V or 5 V host controller. Its open-drain outputs and sub-5 ns delay make it suitable for I2C and other bidirectional serial buses in consumer, industrial, and embedded designs.

Frequently Asked Questions
How fast does signal propagation occur through the TXS0102DQER when translating logic levels?
The TXS0102DQER has a maximum propagation delay of 4.4 ns and provides 2-bit bidirectional translation with open-drain outputs, making it fast enough for I2C and other serial buses running at typical clock rates up to 400 kHz.
How small is the TXS0102DQER's footprint compared to a standard SOIC-8 level shifter?
This translator is housed in an 8-pin QFN small-outline no-lead package, which typically occupies roughly 40% less board area than a standard 8-pin SOIC package while supporting the same 2-bit signal count.
Why would engineers connect the TXS0102DQER between a 1.8 V sensor and a 3.3 V microcontroller instead of using a resistor divider?
Because the TXS0102DQER performs active bidirectional level translation with open-drain outputs and only a 4.4 ns delay, it reliably shifts signals between voltage domains such as 1.8 V and 3.3 V without the signal degradation or speed loss common to simple resistor-divider circuits.
