Key Features
- Bidirectional Level Translation: Enables level translation between different voltage levels, making it suitable for various low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V).
- Dual-Supply Pins: Both VCC(A) and VCC(B) can be supplied at any voltage between 0.8 V and 3.6 V.
- Direction Control: A HIGH on the DIR input allows transmission from nA to nB, while a LOW allows transmission from nB to nA.
- Partial Power-Down Capability: The device is fully specified for partial power-down applications using IOFF circuitry, preventing backflow current when powered down.
- High Noise Immunity: Specified to operate from -40 °C to +125 °C.
Applications
- Mixed Voltage Systems: Ideal for systems that require communication between different voltage domains.
- Interface Translation: Suitable for translating signals between different logic families such as CMOS and LVTTL.
- Power Management Systems: Useful in systems where partial power-down is necessary to conserve energy.
- Industrial and Automotive Systems: Robust operation over a wide temperature range makes it suitable for industrial and automotive applications.
