SN74LVTH540DWR

具有三态输出的 3.3V ABT 八路缓冲器/驱动器 20-SOIC -40 to 85

description/ordering information

These octal buffers/drivers are designed specifically for low-voltage 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

The ’LVTH540 devices are ideal for driving bus lines or buffer-memory address registers. These devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board layout.

• Support Mixed-Mode Signal Operation 5-V Input and Output Voltages With 3.3-V VCC

• Typical VOLP Output Ground Bounce

  <0.8 V at VCC = 3.3 V, TA = 25°C

• Support Unregulated Battery Operation Down to 2.7 V

• Ioff and Power-Up 3-State Support Hot Insertion

• Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors

• Latch-Up Performance Exceeds 500 mA Per JESD 17

• ESD Protection Exceeds JESD 22
