Note 5: The output pins RST and RST have an internal pull-up to V
typically –6 A. However, an external pull-up resistor may be used when
faster rise time is required or for V
Note 6: The input current to the three-state input pins are the pull-up and
the pull-down current when the pins are either set to V1 or GND
respectively. In the open state, the maximum leakage current to V1 or GND
permissible is 10 A.
