#172410 - pull-up or other chip? Responding to: ???'s previous message |
Why not look into any of the 8051 chips that also supports push-pull of I/O pins.
Another thing is that you can also add an external pull-up resistor. The disadvantage is that the processor must then sink the current from the pull-up resistor to hold the signal low so you get a higher current consumption than with a pull-pull design. |
