Pull-up resistor is the input current, pull-down is the output current; the resistance value of the pull-up resistor is different from that of the pull-down resistor, there is no strict distinction; the ability to provide current and voltage for non-collector (or drain) open-circuit output...
To calculate the pull-down resistor value, it’s slightly different from the pull-up resistor value. Knowing that current is 100uA, we’ll take 0.5v as our pull-down voltage since the input is 0.8v. Thus, applying our R = V/I once again, but this time we don’t have to minus, ...
Pull up is to clamp an uncertain signal to a high level with a resistor, and the resistor also acts as a current limiter. In the same way, pull down m...
Pull-up and Pull-down Resistor Values The appropriate value for the pull-up (or pull-down) resistor is limited by two factors. The first factor is power dissipation. If the resistance value is too low, a high current will flow through the pull-up resistor, heating the device and using ...

Pull down resistor Mosfet gate是 high impedence,非常 sensitive,一個雜訊就可能誤動作, 所以需接一個 pull down resitor 到地,穩住 level。 Reference https://www.crifan.com/order_open-drain_push-pull_mosfet_mos_tube_transistors_and_other_basic_knowledge/...
For single gate or standard inputs of pull-up resistors, the maximum value for the resistor can be calculated as: For multiple logic gates with pull-up resistors, the current can be multiplied by the number of logic gates. Comparison of Pull-up and Pull-Down Resistors ...
