The 74LVT244A is designed with an input impedance of 5 kΩ, and an I/O impedance of 500 Ω, which reduces power consumption while maintaining high-impedance inputs. The device also supports live insertion and withdrawal (partial-power-down mode) which minimizes device damage during high current switching.

This product is also characterized for operation from -40°C to +85°C, making it reliable for industrial temperature ranges. The 74LVT244A offers a power-off disable feature ensuring no excessive current drain from the input or output during power-down situations. The device is available in a variety of packages, ensuring flexibility for specific design needs.

Applications:

• Memory address drivers
• Clock drivers
• Bus transceivers
• Bus-oriented systems
