The SN74LS244DWRG4 is a high-performance, octal buffer and line driver designed to interface with 8-bit microprocessors and standard TTL logic families. Manufactured by Texas Instruments, this integrated circuit is part of the 74LS family, known for its low power consumption and high speed. It is specifically created to improve the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

Key Features:

• Logic Type: Octal Buffer/Line Driver with 3-State Outputs
• Number of Channels: 8
• Output Type: 3-State
• Supply Voltage: 4.75 V to 5.25 V
• Operating Temperature Range: -40°C to 85°C
• Package / Case: SOIC-20
• Mounting Type: Surface Mount

The SN74LS244DWRG4 features two sets of eight buffers with separate output-enable (OE) inputs for each set. This allows for greater flexibility in controlling the interface of bus lines or buffer memory address registers. When the OE input is low, the device passes the data from the input to the output, and when high, the output is in a high-impedance state, effectively disconnecting the output from the bus. This high-impedance state is crucial for bus-driven applications, allowing multiple devices to share the same bus lines without interference.

Applications:

• Memory address drivers
• Bus-oriented systems
• Buffer memory address registers
• Clock drivers

With its wide operating temperature range and surface-mount package, the SN74LS244DWRG4 is suitable for a variety of industrial and commercial applications where robust performance is required. The device's fast propagation delay and setup times are essential for high-speed systems, while its low power consumption makes it an efficient choice for power-sensitive designs.
