operating current of the light-emitting diode is 5 ~ 10mA ).
Up/down resistance
I. Definition
1. Pulling up is to embed uncertain signals in a high level through a resistor! "Resistance simultaneously throttling "! The same is true for the drop-down!
2. the pull-up operation injects current into the device, and the drop-down operation is the output current.
3. the weak ones only have different resistance values for the pull-up
other high-speed chips, when used to view the chip manual is OK.TTL usage Note: TTL level is generally more severe overshoot, may be at the beginning of the string 22 Kohm or 33 ohms, TTL level input pin is internally considered high level. To drop the words apply 1k below the resistor drop down.
