The 74AUP1T34 is a single-bit, dual-supply, noninverting buffer translator suitable for transmitting a single logic bit across different voltage domains. It is a unidirectional translator from A to Y. The input pin A has input switching thresholds related to VCCA, operating from 0.9V to 3.6V. The output pin Y has a HIGH level output voltage that tracks VCCB, also operating from 0.9V to 3.6V. This arrangement allows for universal low-voltage translation between any voltages from 0.9V to 3.6V.
The three-state feature occurs when the VCCA power-supply voltages are zero. This is also an IOFF feature and allows the output to remain in a high-impedance state, preventing damaging backflow currents and providing power-down electrical isolation of up to 3.6V. If the VCCB is at ground, the input circuits at pin A are disabled and no input current flows regardless of any applied voltage between 0V and 3.6V.
The 74AUP1T34 is available in the SOT353, X2-DFN1410-6, and X2- DFN1010-6 packages, and is specified for operation from -40°C to +125°C among all supply voltages. The wide temperature ranges and high ESD tolerance facilitate their use in harsh applications.
