Key Features
- Mixed-Mode Signal Operation: Supports 5-V input and output voltages with 3.3-V VCC.
- Low-Voltage Operation: Operates down to 2.7 V, making it suitable for unregulated battery operation.
- Bus Hold Circuitry: Eliminates the need for external pullup/pulldown resistors by holding unused or undriven inputs at a valid logic state.
- 3-State Outputs: Each output is in the high-impedance state when the associated output-enable (OE) input is high.
- Hot Insertion Support: Features Ioff and power-up 3-state support, preventing damaging current backflow and driver conflict during power up and down.
- ESD Protection: Exceeds JESD 22 standards with 2000-V Human-Body Model and 200-V Machine Model protection.
- Latch-Up Performance: Exceeds 500 mA per JESD 17.
Applications
The SN74LVTH125PWR is versatile and can be used in various applications, including:
- Mixed-Voltage Systems: Ideal for systems that require interface between 3.3-V and 5-V logic levels.
- Low-Power Designs: Suitable for battery-operated devices and other low-power applications due to its low voltage operation.
- High-Speed Data Transmission: Used in high-speed data transmission systems where fast switching and low noise are critical.
- Embedded Systems: Can be integrated into embedded systems requiring reliable and efficient signal buffering and line driving.
