Pinout
Key functions include:
- It has four independent buffer gates.
- Each gate features its own output enable pin, allowing for more precise control of each buffer.
- When the output enable pin is low, the corresponding buffer outputs are enabled and follow the input logic state.
- When the output enable pin is high, the buffer outputs are in a high-impedance state, effectively disconnecting them from the circuit.
This device is commonly used in digital circuits for buffering, driving bus lines, and level shifting applications. It is compatible with TTL logic levels, making it suitable for interfacing between different logic families.
