Texas Instruments TXG102x Ground-Level Translators
Texas Instruments TXG102x Ground-Level Translators are 2-bit devices that support DC shifts up to ±10V and feature fixed direction and non-galvanic-based voltage. These ground-level translators support both logic-level shifting between 1.71V and 5.5V, as well as ground-level shifting of up to ±10V. The TXG102x ground-level translators help improve noise immunity and power sequencing across different ground domains while providing low power consumption, latency, and channel-to-channel skew. These ground-level translators can support multiple interfaces, including UART, GPIO, and JTAG. The TXG102x ground-level translators operate at -40°C to 125°C operating temperature range. These ground-level translators are ideal for test and measurement, industrial automation, and robotics.
