The TXG8010-Q1 is a 1-bit, fixed direction, non-galvanic based voltage and ground-level translator that can support both logic-level shifting between 1.71V to 5.5V and ground-level shifting up to ±80V. Compared to traditional level shifters, the TXG8010-Q1 family can solve the challenges of voltage translation across different ground levels. The Simplified Diagram shows a common use case where DC shift occurs between GNDA to GNDB due to parasitic resistance or capacitance.

VCCA is referenced to GNDA and VCCB is referenced to GNDB. Ax pins are referenced to VCCA logic level while Bx pins are referenced to VCCB logic levels. Both A port and B port can accept voltages from 1.71V to 5.5V.

The TXG8010-Q1 device helps improve noise immunity and power sequencing across different ground domains while providing low power consumption, latency and channel-to-channel skew. It can supress noise levels of 140VPP up to 1MHz (Figure 7-4). This device can support multiple interfaces such as UART, GPIO, and JTAG.
