DC Control Logic
* To prevent reversal of current during fast decay SR – the outputs will go to the high impedance state as the current gets near zero.
For input and output current specifications, negative current is defined as coming out of (sourcing) the specified device pin.
Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions. Performance may vary for indi-
