Functional Features

• High-speed operation: The 74LVT16244BEV,157 is designed to operate at high speeds, making it suitable for applications requiring fast data transmission.
• Tri-state outputs: The IC has tri-state outputs, allowing multiple devices to share a common bus without interfering with each other.
• Non-inverting: The buffer/driver does not invert the input signal, maintaining its original logic level at the output.

Advantages and Disadvantages

Advantages:

• High-speed operation enables efficient data transmission.
• Tri-state outputs facilitate bus sharing in multi-device systems.
• Non-inverting nature preserves the logic level of the input signal.

Disadvantages:

• Limited supply voltage range (2.7V to 3.6V) may restrict compatibility with certain systems.
• Propagation delay time of 4.5ns (max) may introduce slight delays in critical applications.

Working Principles

The 74LVT16244BEV,157 is a CMOS buffer/driver that amplifies and buffers digital signals. It operates by receiving an input signal and providing a corresponding amplified output signal. The tri-state outputs allow the IC to be connected to a common bus, where it can either drive the bus with its output or enter a high-impedance state, effectively disconnecting from the bus.
