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
