74AUP1T34数据手册集成电路（IC）的转换器电平移位器规格书PDF

描述 Description

The 74AUP1T34 is a single-bit, dual-supply, non-inverting buffer translator suitable for transmitting a single logic bit acrossdifferent voltage domains. It is a uni-directional translator from A to Y. The input Pin A has input switching thresholds related to VCCA, operating from 0.9 V to 3.6 V. 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 0 and 3.6V.

The 74AUP1T34 is available in the SOT353, X2-DFN1410, and X2-DFN1010 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.
