Description

The SN74AUP1T34 is a 1-bit noninverting translator with two independently configurable power supply rails. It is a one-way translator from A to B. The A port is intended to monitor VCCA. The supply voltage range for VCCA is 0.9 V to 3.6 V. The B port is intended to monitor VCCB. VCCB can accept supply voltages ranging from 0.9 V to 3.6 V. This enables low-voltage translation between voltage nodes of 1 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. The SN74AUP1T34 is also fully specified for Ioff-based partial-power-down applications. When the device is turned off, the Ioff circuitry disables the outputs, preventing damaging current backflow through the device.

Features

• Input Hysteresis Allows Slow Input Transition and Better Switching Noise Immunity at Input
• ESD Protection Exceeds JESD 22
• 5000-V Human-Body Model (A114-A)
• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
• Wide Operating VCC Range of 0.9 V to 3.6 V • Balanced Propagation Delays: tPLH = tPHL (1.8-V to 3.3-V Translation Typical)
• Low Static-Power Consumption: Maximum of 5-µA ICC
• ±6-mA Output Drive at 3 V • Ioff Supports Partial Power-Down-Mode Operation
• VCC Isolation Feature – If VCCA Input Is at GND, B Port Is in the High-Impedance state
