The TXG404x-Q1 is a 4-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 ±40V. Compared to traditional level shifters, the TXG404x-Q1 family can solve the challenges of voltage translation across different ground levels. The Simplified Block Diagram shows a common use case where there is a DC shift 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 levels 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 max leakage between GNDA and GNDB is 2µA when VCC to GND is shorted.

The TXG404x-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 at 130VPP up to 1MHz (Figure 6-1). This device can support multiple interfaces such as SPI, UART, GPIO, and I2S.
