I have a couple of these http://www.toshiba.com/taec/components2/Datasheet_Sync//149/215.pdf I am using for level shifting 3.3 volts to 5v from a beaglebone to a stepper motor driver. The frequencies will range between 2.5kHz - 800 hZ. My questions are:
1) Do I need capacitors, and what would be good values?
2) The datasheet lists DC Vcc/GND current MAX as += 200mA, does this mean I need a current limiting resistor in series with my 5v line (Vcc) and Vcc pin? My TA says I don't, but I would like to double check.
3) For one of the IC's I want to tie the inputs to Vcc and use a Oen (G1/G2) to toggle them all at once. Do I need current limiters between Vcc and the input pins? Again my TA says I don't, but it would be nice to have a good explanation and another opinion.
The stepper driver draws between 8mA-16mA and has a 240 ohm resistor in series with it's inputs.
