The DIR pin (pin 1) of SN74LVC245A has to be configured to control the direction of the data flow . what is the value of pull up/down resistor to be considered.
should i limit the current to
Ii(Control input) ±5 m A(Max) or
IIK Input clamp current –50 mA(Max) or can i directly connect the pin to vcc or gnd.
