The TXG804x is a 4-bit, fixed direction, non-galvanic based voltage and ground-level translator that supports both logic-level shifting between 1.71V to 5.5V and ground-level shifting up to ±80V. Compared to traditional level shifters, the TXG804x family solves 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 accept voltages from 1.71V to 5.5V. This device includes two enable pins that place the respective outputs in a high-impedance state when the OE pin is connected to GND or left floating. In the event of input power or signal loss, the output is default low when OE is High (refer to ). The leakage between GNDA and GNDB is 70nA when VCC to GND is shorted.

The TXG804x device helps improve noise immunity and power sequencing across different ground domains while providing low power consumption, latency, and channel-to-channel skew. TXG804x supresses noise levels of 140PP up to 1MHz (Figure 7-3). This device supports multiple interfaces such as SPI, UART, GPIO, and I2S.
