Descriptions:

The SN74LS244DBR is an octal buffer and line driver designed with 3-state outputs. It is part of the 74LS logic family, providing improved speed and lower power consumption compared to standard TTL. The device features two independent 4-bit buffers with separate output-enable (OE) inputs, allowing flexible control.

Features:

  • Octal Buffer/Line Driver with 3-State Outputs
  • Two 4-Bit Buffers with Separate Output Enables
  • High-Current Outputs for Driving Bus Lines
  • Wide Operating Voltage Range (4.75V to 5.25V)
  • Low Power Consumption (LS Technology)
  • Fast Propagation Delay (15ns max)
  • Surface-Mount SSOP-20 Package
  • Compatible with TTL Input/Output Levels

This device is commonly used in bus-oriented applications where buffering and signal isolation are required.
