The TC74HC125AF(EL) is a high-speed quad buffer with three-state outputs from Toshiba Semiconductor and Storage, belonging to the High-speed CMOS (HC) logic family. This device operates with a supply voltage of 2V to 6V. It is designed for buffering signals and driving bus lines in digital systems. The three-state outputs allow multiple devices to share a common bus by enabling or disabling their outputs. The device features separate enable inputs for each buffer, providing flexibility in controlling individual outputs.

Applications:

• Bus driving and buffering
• Data line isolation
• Memory address buffering
• Input/Output port expansion
• Level shifting

Features:

• High-speed operation: tpd = 9 ns (typ.) at VCC = 5V
• Wide operating voltage range: VCC = 2V to 6V
• Low power consumption: ICC = 1 μA (max.) at VCC = 5V
• Three-state outputs
• Separate enable inputs for each buffer
• Symmetrical output drive: |IOH| = IOL = 4 mA
• Wide operating temperature range: -40°C to +85°C
• Package: SOIC14 (Small Outline Integrated Circuit)

Benefits:

• Improved system performance due to high-speed operation
• Energy efficiency due to low power consumption
• Flexibility in controlling individual outputs
• Bus isolation to prevent signal conflicts
• Suitable for a wide range of voltage levels
• Directly drives LEDs and other low-current loads
• Compact size for space-constrained applications
