74F244** is a high-speed octal buffer and line driver manufactured by **Texas Instruments (TI)**.

The 74F244 is a high-speed octal buffer and line driver manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

Specifications:

  • Logic Family: 74F (Fast TTL)
  • Function: Octal Buffer/Line Driver (3-State)
  • Number of Channels: 8 (Octal)
  • Input/Output Type: TTL-Compatible
  • Supply Voltage (VCC): 4.5V to 5.5V (Nominal 5V)
  • Output Current (High/Low): ±15mA (Sink/Source)
  • Propagation Delay: Typically 4.5ns (Max 7ns at 5V)
  • Operating Temperature Range: 0°C to +70°C (Commercial Grade)
  • Package Options: 20-pin PDIP, SOIC, SSOP, and others
  • Output Type: 3-State (High, Low, High-Impedance)

Descriptions:

  • The 74F244 is designed for bus-oriented applications where buffering and driving capabilities are required.
  • It features two independent 4-bit buffers with separate output enable controls (1G and 2G).
  • The 3-state outputs allow multiple devices to share a common bus without interference.
  • It is optimized for high-speed operation, making it suitable for microprocessor and memory interfacing.

Features:

  • High-Speed Performance: Fast propagation delay (4.5ns typical).
  • 3-State Outputs: Allows bus sharing in multi-device systems.
  • High Drive Capability: Supports up to ±15mA output current.
  • TTL-Compatible Inputs & Outputs: Ensures compatibility with standard logic levels.
  • Separate Output Enable Controls: Two active-low enable pins (1G, 2G) for independent buffer control.
  • Wide Operating Voltage: Supports 4.5V to 5.5V operation.

This device is commonly used in digital systems, data buses, and buffering applications where signal integrity and speed are critical.
