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.
