Relationship between Enable, RESET and Output (OUT and MO)
accordance with input clock signals and without regard to the ENABLE signal. Therefore output current is
initiated by the timing of the internal logic circuit after release of disable mode.
state: A Channel output current is 100%).
next raise in the Clock signal.
The ENABLE signal at Low level disables only the output signals. Internal logic functions proceed in
When the RESET signal goes Low level, output goes Initial state and the MO output goes Low level (Initial
Once the RESET signal returns to High level, output continues from the next state after Initial from the
