The TXGS441-SEP is a ±40V, 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 ±40V. Compared to traditional level shifters, the TXGS441-SEP 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. This device includes two enable pins that can 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 45nA when VCC to GND is shorted.

The TXGS441-SEP 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 suppress noise levels of 80VPP up to 5MHz (Figure 7-3). This device can support multiple interfaces such as SPI, UART, GPIO, and I2S.
