Pinout
Here is a brief overview of its pin configuration and function:
1. Pin 1 and Pin 4: Output Enable Inputs (1OE and 2OE) - These are active-low inputs that control the state of the corresponding outputs. When low, the output is enabled; when high, the output is in a high-impedance state.
2. Pin 2 and Pin 5: Data Inputs (1A and 2A) - These are the data inputs for each buffer.
3. Pin 3 and Pin 6: Outputs (1Y and 2Y) - These are the outputs for each buffer. The state of these pins depends on the input and the output enable pin.
4. Pin 7: Ground (GND) - Connects to the ground of the circuit.
5. Pin 8: Supply Voltage (VCC) - Connects to the positive supply voltage.
The 74HC2G125DP is utilized in applications where buffering and isolation of digital signals are required.
