For this matter, 2003 integrated block (IC) pin parameters can vary depending on the specific chip model. However, in general, the common pin parameters for 2003 integration blocks are as follows:
1. Vcc (positive power supply) : Supply the positive power supply pin, usually connected to the positive power supply voltage.
2. GND (ground) : Ground pin, usually connected to the circuit ground point.
3. IN1 (Input 1) : Input signal pin 1, used to input control signals.
4. IN2 (Input 2) : Input signal pin 2, used to input control signals.
5. OUT1 (Output 1) : Output pin 1, used to output the control signal.
6. OUT2 (Output 2) : Output pin 2, used to output the control signal.
It should be noted that the pin definition of the specific chip may be different, and the above is only a general case of the pin parameters. For pin definitions for a specific chip, refer to the chip's data manual or technical specification.
