Use and aesthetics

The output terminal is high prior to powering on; 3. The "falling edge" trigger of the trigger terminal is valid, and the output terminal immediately becomes low level after the trigger, and the circuit begins timing; 4. After the set timing time is up, the output terminal will return to high level, waiting for the next "falling edge" trigger; and 5. The chip is in the circuit.
