Texas Instruments TXG104x 4-Bit Ground-Level Translator is a fixed-direction, non-galvanic-based voltage and ground-level translator supporting logic-level shifting between 1.71V and 5.5V and ground-level shifting up to ±10V. Compared to traditional level shifters, the TXG104x family can solve the challenges of voltage translation across different ground levels. VCCA is referenced to GNDA, and VCCB is referenced to GNDB. Ax pins are referenced to the VCCA logic level, while Bx pins are referenced to the VCCB logic level. 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 set to a default low when OE is High. The leakage between GNDA and GNDB is < 30nA when VCC to GND is shorted.
