Pinout
The LM239PT typically comes in a 14-pin package. Here's a brief overview of its pin configuration and functions:
1. V+ (Pin 3): Positive supply voltage.
2. GND (Pin 12): Ground connection.
3. Output (Pins 1, 7, 8, 14): Outputs of the four comparators.
4. Inverting Inputs (Pins 2, 6, 9, 13): Negative inputs for the comparators.
5. Non-inverting Inputs (Pins 4, 5, 10, 11): Positive inputs for the comparators.
Each comparator within the LM239PT compares the voltage between its non-inverting and inverting inputs and provides a digital output based on which input is higher.
The LM239PT can operate over a wide range of supply voltages and is suitable for industrial applications due to its robustness and ability to handle various voltage levels efficiently.
