Key Features
- Output Enable and Direction Control: The device includes an output enable (OE) and a send/receive (DIR) pin, allowing for control over the direction of data transfer and enabling the outputs to assume a high-impedance OFF-state when OE is HIGH.
- Bus Hold Data Inputs: Eliminates the need for external pull-up resistors to define unused inputs.
- Overvoltage Tolerant Inputs: Inputs are tolerant up to 5.5 V.
- BiCMOS High Speed and Output Drive: Provides high-speed operation and robust output drive capability of +64 mA/-32 mA.
- Latch-up Protection: Exceeds 500 mA per JESD78 class II level A.
- Live Insertion/Extraction Permitted: Allows for safe insertion and extraction of the device in live systems.
- Power-up 3-state and Partial Power-down Mode Operation: Supports power-up 3-state and partial power-down mode operation.
