SN74LS244NSRG4 Octal Buffers/Drivers with 3-State Outputs

The SN74LS244NSRG4 is a high-performance, octal buffer and line driver designed to interface with 5V digital systems. Manufactured by Texas Instruments, this integrated circuit is part of the 74LS family, which is known for its low-power Schottky technology. It provides a robust solution for driving bus lines or buffering memory address registers with its bidirectional interface and 3-state outputs.

Key Features

• Logic Family: LS - Low-power Schottky
• Logic Type: Octal Buffer/Line Driver with 3-State Outputs
• Number of Pins: 20
• Package: NSR - Plastic Shrink Small Outline (SSOP)
• Operating Temperature: 0°C to 70°C
• Supply Voltage: 4.75V to 5.25V

Performance Characteristics

The SN74LS244NSRG4 features two sets of eight buffers with separate output-enable (OE) inputs for each set. When the OE input is low, the device passes the input data to the output. Conversely, when OE is high, the output enters a high-impedance state, effectively isolating the bus line.

The device boasts a typical propagation delay time of 10ns, ensuring fast response times in critical applications. The low-power consumption of the LS technology makes it suitable for power-sensitive designs, while the high-current outputs can drive up to 15 LSTTL loads, providing ample driving capability for connected components.

Applications

The SN74LS244NSRG4 is versatile and can be used in a wide range of applications, including:

• Memory address drivers
• Data transmission lines
• Bus-oriented systems
• Input/output port drivers

Quality and Reliability

Texas Instruments is committed to delivering high-quality products. The SN74LS244NSRG4 is no exception, offering reliable performance and consistency across different environmental conditions. Its robust plastic shrink small outline package ensures durability and ease of integration into various designs.

In summary, the SN74LS244NSRG4 from Texas Instruments is an essential component for designers looking for a reliable octal buffer/driver with the flexibility of 3-state outputs. Its compatibility with 5V systems and its ability to isolate bus lines when not in use make it an excellent choice for complex digital systems requiring high-speed data transfer and interfacing.
