Pinout
Here’s a brief overview of the pin functionality:
- Pins 1, 4, 9, 12: Inputs for the four OR gates (A1, A2, A3, A4).
- Pins 2, 5, 10, 13: Second inputs for the four OR gates (B1, B2, B3, B4).
- Pins 3, 6, 8, 11: Outputs for the four OR gates (Y1, Y2, Y3, Y4).
- Pin 7: Ground (GND), connected to the negative supply voltage.
- Pin 14: Positive supply voltage (VCC).
The SN74LS32N is designed for use in TTL (Transistor-Transistor Logic) applications, providing reliable performance in various digital circuits by outputting a high signal when any one or more of its inputs are high.
