The SN74LVTH244A from Texas Instruments is a high-performance, octal buffer and line driver designed to facilitate the transmission of data over high-capacity communication lines with minimal signal distortion. This device is part of the LVTH family, which means it operates at a lower voltage with higher transfer rates, making it suitable for interfacing with 3.3V and 5V systems.

Featuring eight non-inverting buffers and line drivers with 3-state outputs, the SN74LVTH244A can be used in a wide array of applications, including driving bus lines or buffering memory address registers. Its 3-state outputs ensure that multiple units can be connected to a bus, as they can be placed in a high-impedance state, effectively disconnecting them from the bus.

Key Features:

• Support for mixed-mode voltage operation (3.3V and 5V).
• High drive capability with outputs that can sink up to 64 mA and source up to 32 mA.
• Low-power consumption characterized by a typical ICC of only 0.8 mA.
• Non-inverting outputs with bus-hold data inputs to eliminate the need for external pull-up resistors.
• Flow-through architecture to optimize PCB layout.
• Power-off protection provided on all inputs and outputs.
• Latch-up performance that exceeds 250 mA per JESD 17.

The SN74LVTH244A is available in a variety of packages, including the TSSOP (Thin Shrink Small Outline Package) and the DB (DIP) package, making it versatile for different physical configurations and space constraints. Its robust design ensures signal integrity, even in environments with high electrical noise, while the low-voltage operation helps in reducing power consumption, making it an excellent choice for energy-efficient and high-speed data transfer systems.
