These octal flip-flops 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 eight flip-flops of the ’LVTH574 devices are edge-triggered D-type flip-flops. On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels set up at the data (D) inputs.
• Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC)
• Support Unregulated Battery Operation Down to 2.7 V
• Typical VOLP (Output Ground Bounce)
<0.8 V at VCC = 3.3 V, TA = 25°C
• Ioff and Power-Up 3-State Support Hot
Insertion
• Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
