Key Features
- 3-State Outputs: The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs, allowing for high-impedance OFF-state when nOE is HIGH.
- Wide Supply Voltage Range: Operates from 1.2 V to 3.6 V, making it suitable for mixed 3.3 V and 5 V environments.
- CMOS Low-Power Consumption: Low power consumption, which is beneficial for energy-efficient designs.
- Overvoltage Tolerant Inputs: Inputs can be driven from either 3.3 V or 5 V devices, and are tolerant up to 5.5 V.
- Schmitt-Trigger Action: Inputs have Schmitt-trigger action, making the circuit tolerant of slower input rise and fall times.
- IOFF Circuitry: Provides partial power-down mode operation, preventing backflow current when the device is powered down.
- Bus Hold on Data Inputs: Available on the 74LVCH244A variant, ensuring that the inputs are held at the last valid state.
Applications
- Data Transmission and Signal Buffering: Ideal for buffering and driving data in digital systems, ensuring signal integrity over long distances.
- Mixed Voltage Environments: Suitable for use in mixed 3.3 V and 5 V environments, acting as a translator between different voltage levels.
- Low-Power Designs: Used in energy-efficient designs where low power consumption is critical.
- Automotive and Industrial Systems: Operates over a wide temperature range (-40°C to 125°C), making it suitable for automotive and industrial applications.
