S6J3200
S6J3300
S6J3350
S6J3360
S6J3370
S6J3400
S6J3510
CY9D560
2.Product prefix "MB" has been changed to "CY".
Answer:
Leaving unused input pins open may cause permanent damage from a malfunction or latch-up. Take measures for unused pins such as pulling up or pulling down the voltage with resistors of 2 kilo ohms or higher.
If there are any unused input/output pins, set them to the output state and then open them, or set them to the input state and handle them in the same way as input pins.
