Key Features
- Bidirectional Level Translation: Enables translation between any of the low-voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V).
- Direction Control and Output Enable: Features a direction control input (DIR) and an output enable input (OE) for flexible data transmission and control.
- Partial Power-Down Mode: IOFF circuitry disables the output, preventing backflow current when the device is powered down.
- High-impedance OFF-State: In suspend mode, both An and Bn are in the high-impedance OFF-state when either VCC(A) or VCC(B) are at GND level.
- ESD Protection: HBM: ANSI/ESDA/JEDEC JS-001 class 3B exceeds 8000 V.
- Compliance with JEDEC Standards: JESD8-12, JESD8-11, JESD8-7, JESD8-5, and JESD8-B.
