DIO74134数据手册DIOO中文资料规格书

描述 Description

DIO74134 is a 1-bit level conversion device with two independent configurable power rails. As a uni-directional translator from A to B, the A port is designed to track VCCA, and the B port is designed to track VCCB. Both VCCA and VCCB accept a power supply voltage of 1.08V to 3.6V. This allows for low-voltage translation between 1.08V, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V Voltage nodes. Also DIO74134 is fully designated for partial power-off applications using Ioff. The Ioff circuit disables the output, preventing destructive current flow back when the device is powered off. \
The VCC isolation feature ensures that if VCCA input is at GND, the B port is in the high-impedance state. If VCCB input is at GND, any input to the A side will not cause the leakage current even floating.

特性 Features

• Operating VCC Range : 1.08V to 3.6V
• Balanced Propagation Delays: tPLH = tPHL (1.8V to 3.3V Translation Typical)
• Output Drive current: ±6mA at 3V
• Low Static-Power Consumption: Maximum of 20µA ICC
• Supports Partial Power-Down-Mode Operation
• VCC Isolation Feature: If VCCA Input is at GND, B Port Is in the High-Impedance state
• Input Hysteresis Allows Slow Input Transition and Better Switching Noise Immunity at Input
• Packaged in SC70-5, DFN1.45*1-6 and DFN1*1-6
