Description of Terminal
Note:
• Mount ICs to the printed circuit board for use. (If the ICs are not mounted to the printed circuit board, the characteristics of ICs may
• Mount 0.1µF capacitors in the vicinity of the IC PINs between 1&2 PIN and 3PIN, 13PIN and 14&15PIN, and 17PIN and 18PIN.
• Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to verify circuit
• Jitters TYP values vary with the substrate, power supply, output loads, noises, and other. For the use, the operating margin should be
