Functional Features

The SN74LVTH244ADWG4 is a high-speed buffer and line driver IC designed for low voltage applications. It features tri-state outputs, which allow multiple devices to share the same bus without interfering with each other. The output enable (OE) pins control the tri-state outputs, enabling or disabling the device.

Advantages and Disadvantages

Advantages: - High-speed operation - Low voltage operation - Tri-state outputs for bus sharing - Wide operating temperature range

Disadvantages: - Limited output current capacity - Requires external pull-up resistors for proper operation

Working Principles

The SN74LVTH244ADWG4 operates by receiving input signals on its bidirectional I/O pins and amplifying them to the appropriate voltage levels. The tri-state outputs allow the device to be connected to a shared bus, where it can drive or receive signals from other devices. The output enable pins control the state of the outputs, either enabling them to drive the bus or disabling them to enter a high-impedance state.
