Key Features
- Wide Operating Voltage Range: Operates from 2 V to 5.5 V, allowing for mixed-mode voltage operation on all ports.
- 3-State Outputs: Outputs can be set to a high-impedance state, controlled by two-input AND gate with active-low inputs.
- Low Propagation Delay: Maximum propagation delay of 6 ns at 5 V.
- Low Output Ground Bounce and VOH Undershoot: Typical VOLP < 0.8 V at VCC = 3.3 V, TA = 25°C, and VOHV > 2.3 V at VCC = 3.3 V, TA = 25°C.
- Ioff Feature: Supports partial-power-down mode operation, disabling outputs to prevent current backflow when powered down.
- ESD Protection: Exceeds JESD 22 standards with 3000-V Human-Body Model, 200-V Machine Model, and 2000-V Charged-Device Model.
