Design information.
Guaranteed by characterization in the development phase. Parameter not tested.
Sleep recovery time is the time from EN going high until the outputs are ready to respond to input. This time is dependent on the recovery
time of V
clearing of the POR condition
By design, if the RS input is left open, the slew time is the same as when shorted to GND. However, this is a high-impedance input and
will be susceptible to external noise sources unless terminated appropriately. It is highly recommended to terminate this pin with either
a ground or one of the program resistors .
