Key Features
- 5 V Tolerant Inputs and Outputs: Allows the device to be used in mixed 3.3 V and 5 V environments.
- 3-State Outputs: Controlled by the output enable inputs (nOE), allowing the outputs to assume a high impedance OFF-state when nOE is HIGH.
- Schmitt-Trigger Action: Tolerant of slower input rise and fall times.
- Wide Supply Voltage Range: From 1.2 V to 3.6 V.
- Low Power Consumption: CMOS technology ensures low power consumption.
- ESD Protection: HBM (Human Body Model) exceeds 2000 V and CDM (Charged Device Model) exceeds 1000 V.
- Partial Power Down Capability: The IOFF circuitry disables the output, preventing backflow current when the device is powered down.
